COMMANDS         top

   add
       hg add [OPTION]... [FILE]...

       Schedule files to be version controlled and added to the
       repository.

       The files will be added to the repository at the next commit. To
       undo an add before that, see hg forget.

       If no names are given, add all files to the repository.

       An example showing how new (unknown) files are added
       automatically by hg add:

       $ ls
       foo.c
       $ hg status
       ? foo.c
       $ hg add
       adding foo.c
       $ hg status
       A foo.c

       Returns 0 if all files are successfully added.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -S, --subrepos
              recurse into subrepositories

       -n, --dry-run
              do not perform actions, just print output

   addremove
       hg addremove [OPTION]... [FILE]...

       Add all new files and remove all missing files from the
       repository.

       New files are ignored if they match any of the patterns in
       .hgignore. As with add, these changes take effect at the next
       commit.

       Use the -s/--similarity option to detect renamed files. This
       option takes a percentage between 0 (disabled) and 100 (files
       must be identical) as its parameter. With a parameter greater
       than 0, this compares every removed file with every added file
       and records those similar enough as renames. Detecting renamed
       files this way can be expensive. After using this option, hg
       status -C can be used to check which files were identified as
       moved or renamed. If not specified, -s/--similarity defaults to
       100 and only renames of identical files are detected.

       Returns 0 if all files are successfully added.

       Options:

       -s, --similarity
              guess renamed files by similarity (0<=s<=100)

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -n, --dry-run
              do not perform actions, just print output

   annotate
       hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...

       List changes in files, showing the revision id responsible for
       each line

       This command is useful for discovering when a change was made and
       by whom.

       Without the -a/--text option, annotate will avoid processing
       files it detects as binary. With -a, annotate will annotate the
       file anyway, although the results will probably be neither useful
       nor desirable.

       Returns 0 on success.

       Options:

       -r, --rev
              annotate the specified revision

       --follow
              follow copies/renames and list the filename (DEPRECATED)

       --no-follow
              don't follow copies and renames

       -a, --text
              treat all files as text

       -u, --user
              list the author (long with -v)

       -f, --file
              list the filename

       -d, --date
              list the date (short with -q)

       -n, --number
              list the revision number (default)

       -c, --changeset
              list the changeset

       -l, --line-number
              show line number at the first appearance

       -w, --ignore-all-space
              ignore white space when comparing lines

       -b, --ignore-space-change
              ignore changes in the amount of white space

       -B, --ignore-blank-lines
              ignore changes whose lines are all blank

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

              aliases: blame

   archive
       hg archive [OPTION]... DEST

       By default, the revision used is the parent of the working
       directory; use -r/--rev to specify a different revision.

       The archive type is automatically detected based on file
       extension (or override using -t/--type).

       Examples:

       • create a zip file containing the 1.0 release:

         hg archive -r 1.0 project-1.0.zip

       • create a tarball excluding .hg files:

         hg archive project.tar.gz -X ".hg*"

       Valid types are:

       files

              a directory full of files (default)

       tar

              tar archive, uncompressed

       tbz2

              tar archive, compressed using bzip2

       tgz

              tar archive, compressed using gzip

       uzip

              zip archive, uncompressed

       zip

              zip archive, compressed using deflate

       The exact name of the destination archive or directory is given
       using a format string; see hg help export for details.

       Each member added to an archive file has a directory prefix
       prepended. Use -p/--prefix to specify a format string for the
       prefix. The default is the basename of the archive, with suffixes
       removed.

       Returns 0 on success.

       Options:

       --no-decode
              do not pass files through decoders

       -p, --prefix
              directory prefix for files in archive

       -r, --rev
              revision to distribute

       -t, --type
              type of distribution to create

       -S, --subrepos
              recurse into subrepositories

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   backout
       hg backout [OPTION]... [-r] REV

       Prepare a new changeset with the effect of REV undone in the
       current working directory.

       If REV is the parent of the working directory, then this new
       changeset is committed automatically. Otherwise, hg needs to
       merge the changes and the merged result is left uncommitted.

       Note   backout cannot be used to fix either an unwanted or
              incorrect merge.

       By default, the pending changeset will have one parent,
       maintaining a linear history. With --merge, the pending changeset
       will instead have two parents: the old parent of the working
       directory and a new child of REV that simply undoes REV.

       Before version 1.7, the behavior without --merge was equivalent
       to specifying --merge followed by hg update --clean . to cancel
       the merge and leave the child of REV as a head to be merged
       separately.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success.

       Options:

       --merge
              merge with old dirstate parent after backout

       --parent
              parent to choose when backing out merge (DEPRECATED)

       -r, --rev
              revision to backout

       -t, --tool
              specify merge tool

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

   bisect
       hg bisect [-gbsr] [-U] [-c CMD] [REV]

       This command helps to find changesets which introduce problems.
       To use, mark the earliest changeset you know exhibits the problem
       as bad, then mark the latest changeset which is free from the
       problem as good. Bisect will update your working directory to a
       revision for testing (unless the -U/--noupdate option is
       specified). Once you have performed tests, mark the working
       directory as good or bad, and bisect will either update to
       another candidate changeset or announce that it has found the bad
       revision.

       As a shortcut, you can also use the revision argument to mark a
       revision as good or bad without checking it out first.

       If you supply a command, it will be used for automatic bisection.
       The environment variable HG_NODE will contain the ID of the
       changeset being tested. The exit status of the command will be
       used to mark revisions as good or bad: status 0 means good, 125
       means to skip the revision, 127 (command not found) will abort
       the bisection, and any other non-zero exit status means the
       revision is bad.

       Some examples:

       • start a bisection with known bad revision 12, and good revision
         34:

         hg bisect --bad 34
         hg bisect --good 12

       • advance the current bisection by marking current revision as
         good or bad:

         hg bisect --good
         hg bisect --bad

       • mark the current revision, or a known revision, to be skipped
         (e.g. if that revision is not usable because of another issue):

         hg bisect --skip
         hg bisect --skip 23

       • skip all revisions that do not touch directories foo or bar

            hg bisect --skip '!( file("path:foo") & file("path:bar") )'

       • forget the current bisection:

         hg bisect --reset

       • use 'make && make tests' to automatically find the first broken
         revision:

         hg bisect --reset
         hg bisect --bad 34
         hg bisect --good 12
         hg bisect --command 'make && make tests'

       • see all changesets whose states are already known in the
         current bisection:

         hg log -r "bisect(pruned)"

       • see the changeset currently being bisected (especially useful
         if running with -U/--noupdate):

         hg log -r "bisect(current)"

       • see all changesets that took part in the current bisection:

         hg log -r "bisect(range)"

       • with the graphlog extension, you can even get a nice graph:

         hg log --graph -r "bisect(range)"

       See hg help revsets for more about the bisect() keyword.

       Returns 0 on success.

       Options:

       -r, --reset
              reset bisect state

       -g, --good
              mark changeset good

       -b, --bad
              mark changeset bad

       -s, --skip
              skip testing changeset

       -e, --extend
              extend the bisect range

       -c, --command
              use command to check changeset state

       -U, --noupdate
              do not update to target

   bookmarks
       hg bookmarks [OPTIONS]... [NAME]...

       Bookmarks are pointers to certain commits that move when
       committing.  Bookmarks are local. They can be renamed, copied and
       deleted. It is possible to use hg merge NAME to merge from a
       given bookmark, and hg update NAME to update to a given bookmark.

       You can use hg bookmark NAME to set a bookmark on the working
       directory's parent revision with the given name. If you specify a
       revision using -r REV (where REV may be an existing bookmark),
       the bookmark is assigned to that revision.

       Bookmarks can be pushed and pulled between repositories (see hg
       help push and hg help pull). This requires both the local and
       remote repositories to support bookmarks. For versions prior to
       1.8, this means the bookmarks extension must be enabled.

       If you set a bookmark called '@', new clones of the repository
       will have that revision checked out (and the bookmark made
       active) by default.

       With -i/--inactive, the new bookmark will not be made the active
       bookmark. If -r/--rev is given, the new bookmark will not be made
       active even if -i/--inactive is not given. If no NAME is given,
       the current active bookmark will be marked inactive.

       Options:

       -f, --force
              force

       -r, --rev
              revision

       -d, --delete
              delete a given bookmark

       -m, --rename
              rename a given bookmark

       -i, --inactive
              mark a bookmark inactive

              aliases: bookmark

   branch
       hg branch [-fC] [NAME]

       Note   Branch names are permanent and global. Use hg bookmark to
              create a light-weight bookmark instead. See hg help
              glossary for more information about named branches and
              bookmarks.

       With no argument, show the current branch name. With one
       argument, set the working directory branch name (the branch will
       not exist in the repository until the next commit). Standard
       practice recommends that primary development take place on the
       'default' branch.

       Unless -f/--force is specified, branch will not let you set a
       branch name that already exists, even if it's inactive.

       Use -C/--clean to reset the working directory branch to that of
       the parent of the working directory, negating a previous branch
       change.

       Use the command hg update to switch to an existing branch. Use hg
       commit --close-branch to mark this branch as closed.

       Returns 0 on success.

       Options:

       -f, --force
              set branch name even if it shadows an existing branch

       -C, --clean
              reset branch name to parent branch name

   branches
       hg branches [-ac]

       List the repository's named branches, indicating which ones are
       inactive. If -c/--closed is specified, also list branches which
       have been marked closed (see hg commit --close-branch).

       If -a/--active is specified, only show active branches. A branch
       is considered active if it contains repository heads.

       Use the command hg update to switch to an existing branch.

       Returns 0.

       Options:

       -a, --active
              show only branches that have unmerged heads

       -c, --closed
              show normal and closed branches

   bundle
       hg bundle [-f] [-t TYPE] [-a] [-r REV]... [--base REV]... FILE [DEST]

       Generate a compressed changegroup file collecting changesets not
       known to be in another repository.

       If you omit the destination repository, then hg assumes the
       destination will have all the nodes you specify with --base
       parameters. To create a bundle containing all changesets, use
       -a/--all (or --base null).

       You can change compression method with the -t/--type option.  The
       available compression methods are: none, bzip2, and gzip (by
       default, bundles are compressed using bzip2).

       The bundle file can then be transferred using conventional means
       and applied to another repository with the unbundle or pull
       command. This is useful when direct push and pull are not
       available or when exporting an entire repository is undesirable.

       Applying bundles preserves all changeset contents including
       permissions, copy/rename information, and revision history.

       Returns 0 on success, 1 if no changes found.

       Options:

       -f, --force
              run even when the destination is unrelated

       -r, --rev
              a changeset intended to be added to the destination

       -b, --branch
              a specific branch you would like to bundle

       --base a base changeset assumed to be available at the
              destination

       -a, --all
              bundle all changesets in the repository

       -t, --type
              bundle compression type to use (default: bzip2)

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

   cat
       hg cat [OPTION]... FILE...

       Print the specified files as they were at the given revision. If
       no revision is given, the parent of the working directory is
       used, or tip if no revision is checked out.

       Output may be to a file, in which case the name of the file is
       given using a format string. The formatting rules are the same as
       for the export command, with the following additions:

       %s

              basename of file being printed

       %d

              dirname of file being printed, or '.' if in repository
              root

       %p

              root-relative path name of file being printed

       Returns 0 on success.

       Options:

       -o, --output
              print output to file with formatted name

       -r, --rev
              print the given revision

       --decode
              apply any matching decode filter

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   clone
       hg clone [OPTION]... SOURCE [DEST]

       Create a copy of an existing repository in a new directory.

       If no destination directory name is specified, it defaults to the
       basename of the source.

       The location of the source is added to the new repository's
       .hg/hgrc file, as the default to be used for future pulls.

       Only local paths and ssh:// URLs are supported as destinations.
       For ssh:// destinations, no working directory or .hg/hgrc will be
       created on the remote side.

       To pull only a subset of changesets, specify one or more
       revisions identifiers with -r/--rev or branches with -b/--branch.
       The resulting clone will contain only the specified changesets
       and their ancestors. These options (or 'clone src#rev dest')
       imply --pull, even for local source repositories. Note that
       specifying a tag will include the tagged changeset but not the
       changeset containing the tag.

       If the source repository has a bookmark called '@' set, that
       revision will be checked out in the new repository by default.

       To check out a particular version, use -u/--update, or
       -U/--noupdate to create a clone with no working directory.

       For efficiency, hardlinks are used for cloning whenever the
       source and destination are on the same filesystem (note this
       applies only to the repository data, not to the working
       directory). Some filesystems, such as AFS, implement hardlinking
       incorrectly, but do not report errors. In these cases, use the
       --pull option to avoid hardlinking.

       In some cases, you can clone repositories and the working
       directory using full hardlinks with

       $ cp -al REPO REPOCLONE

       This is the fastest way to clone, but it is not always safe. The
       operation is not atomic (making sure REPO is not modified during
       the operation is up to you) and you have to make sure your editor
       breaks hardlinks (Emacs and most Linux Kernel tools do so). Also,
       this is not compatible with certain extensions that place their
       metadata under the .hg directory, such as mq.

       Mercurial will update the working directory to the first
       applicable revision from this list:

       a. null if -U or the source repository has no changesets

       b. if -u . and the source repository is local, the first parent
          of the source repository's working directory

       c. the changeset specified with -u (if a branch name, this means
          the latest head of that branch)

       d. the changeset specified with -r

       e. the tipmost head specified with -b

       f. the tipmost head specified with the url#branch source syntax

       g. the revision marked with the '@' bookmark, if present

       h. the tipmost head of the default branch

       i. tip

       Examples:

       • clone a remote repository to a new directory named hg/:

         hg clone http://selenic.com/hg

       • create a lightweight local clone:

         hg clone project/ project-feature/

       • clone from an absolute path on an ssh server (note
         double-slash):

         hg clone ssh://user@server//home/projects/alpha/

       • do a high-speed clone over a LAN while checking out a specified
         version:

         hg clone --uncompressed http://server/repo -u 1.5

       • create a repository without changesets after a particular
         revision:

         hg clone -r 04e544 experimental/ good/

       • clone (and track) a particular named branch:

         hg clone http://selenic.com/hg#stable

       See hg help urls for details on specifying URLs.

       Returns 0 on success.

       Options:

       -U, --noupdate
              the clone will include an empty working copy (only a
              repository)

       -u, --updaterev
              revision, tag or branch to check out

       -r, --rev
              include the specified changeset

       -b, --branch
              clone only the specified branch

       --pull use pull protocol to copy metadata

       --uncompressed
              use uncompressed transfer (fast over LAN)

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

   commit
       hg commit [OPTION]... [FILE]...

       Commit changes to the given files into the repository. Unlike a
       centralized SCM, this operation is a local operation. See hg push
       for a way to actively distribute your changes.

       If a list of files is omitted, all changes reported by hg status
       will be committed.

       If you are committing the result of a merge, do not provide any
       filenames or -I/-X filters.

       If no commit message is specified, Mercurial starts your
       configured editor where you can enter a message. In case your
       commit fails, you will find a backup of your message in
       .hg/last-message.txt.

       The --amend flag can be used to amend the parent of the working
       directory with a new commit that contains the changes in the
       parent in addition to those currently reported by hg status, if
       there are any. The old commit is stored in a backup bundle in
       .hg/strip-backup (see hg help bundle and hg help unbundle on how
       to restore it).

       Message, user and date are taken from the amended commit unless
       specified. When a message isn't specified on the command line,
       the editor will open with the message of the amended commit.

       It is not possible to amend public changesets (see hg help phases
       ) or changesets that have children.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success, 1 if nothing changed.

       Options:

       -A, --addremove
              mark new/missing files as added/removed before committing

       --close-branch
              mark a branch as closed, hiding it from the branch list

       --amend
              amend the parent of the working dir

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

       -S, --subrepos
              recurse into subrepositories

              aliases: ci

   copy
       hg copy [OPTION]... [SOURCE]... DEST

       Mark dest as having copies of source files. If dest is a
       directory, copies are put in that directory. If dest is a file,
       the source must be a single file.

       By default, this command copies the contents of files as they
       exist in the working directory. If invoked with -A/--after, the
       operation is recorded, but no copying is performed.

       This command takes effect with the next commit. To undo a copy
       before that, see hg revert.

       Returns 0 on success, 1 if errors are encountered.

       Options:

       -A, --after
              record a copy that has already occurred

       -f, --force
              forcibly copy over an existing managed file

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -n, --dry-run
              do not perform actions, just print output

              aliases: cp

   diff
       hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...

       Show differences between revisions for the specified files.

       Differences between files are shown using the unified diff
       format.

       Note   diff may generate unexpected results for merges, as it
              will default to comparing against the working directory's
              first parent changeset if no revisions are specified.

       When two revision arguments are given, then changes are shown
       between those revisions. If only one revision is specified then
       that revision is compared to the working directory, and, when no
       revisions are specified, the working directory files are compared
       to its parent.

       Alternatively you can specify -c/--change with a revision to see
       the changes in that changeset relative to its first parent.

       Without the -a/--text option, diff will avoid generating diffs of
       files it detects as binary. With -a, diff will generate a diff
       anyway, probably with undesirable results.

       Use the -g/--git option to generate diffs in the git extended
       diff format. For more information, read hg help diffs.

       Examples:

       • compare a file in the current working directory to its parent:

         hg diff foo.c

       • compare two historical versions of a directory, with rename
         info:

         hg diff --git -r 1.0:1.2 lib/

       • get change stats relative to the last change on some date:

         hg diff --stat -r "date('may 2')"

       • diff all newly-added files that contain a keyword:

         hg diff "set:added() and grep(GNU)"

       • compare a revision and its parents:

         hg diff -c 9353         # compare against first parent
         hg diff -r 9353^:9353   # same using revset syntax
         hg diff -r 9353^2:9353  # compare against the second parent

       Returns 0 on success.

       Options:

       -r, --rev
              revision

       -c, --change
              change made by revision

       -a, --text
              treat all files as text

       -g, --git
              use git extended diff format

       --nodates
              omit dates from diff headers

       -p, --show-function
              show which function each change is in

       --reverse
              produce a diff that undoes the changes

       -w, --ignore-all-space
              ignore white space when comparing lines

       -b, --ignore-space-change
              ignore changes in the amount of white space

       -B, --ignore-blank-lines
              ignore changes whose lines are all blank

       -U, --unified
              number of lines of context to show

       --stat output diffstat-style summary of changes

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -S, --subrepos
              recurse into subrepositories

   export
       hg export [OPTION]... [-o OUTFILESPEC] [-r] [REV]...

       Print the changeset header and diffs for one or more revisions.
       If no revision is given, the parent of the working directory is
       used.

       The information shown in the changeset header is: author, date,
       branch name (if non-default), changeset hash, parent(s) and
       commit comment.

       Note   export may generate unexpected diff output for merge
              changesets, as it will compare the merge changeset against
              its first parent only.

       Output may be to a file, in which case the name of the file is
       given using a format string. The formatting rules are as follows:

       %%

              literal "%" character

       %H

              changeset hash (40 hexadecimal digits)

       %N

              number of patches being generated

       %R

              changeset revision number

       %b

              basename of the exporting repository

       %h

              short-form changeset hash (12 hexadecimal digits)

       %m

              first line of the commit message (only alphanumeric
              characters)

       %n

              zero-padded sequence number, starting at 1

       %r

              zero-padded changeset revision number

       Without the -a/--text option, export will avoid generating diffs
       of files it detects as binary. With -a, export will generate a
       diff anyway, probably with undesirable results.

       Use the -g/--git option to generate diffs in the git extended
       diff format. See hg help diffs for more information.

       With the --switch-parent option, the diff will be against the
       second parent. It can be useful to review a merge.

       Examples:

       • use export and import to transplant a bugfix to the current
         branch:

         hg export -r 9353 | hg import -

       • export all the changesets between two revisions to a file with
         rename information:

         hg export --git -r 123:150 > changes.txt

       • split outgoing changes into a series of patches with
         descriptive names:

         hg export -r "outgoing()" -o "%n-%m.patch"

       Returns 0 on success.

       Options:

       -o, --output
              print output to file with formatted name

       --switch-parent
              diff against the second parent

       -r, --rev
              revisions to export

       -a, --text
              treat all files as text

       -g, --git
              use git extended diff format

       --nodates
              omit dates from diff headers

   forget
       hg forget [OPTION]... FILE...

       Mark the specified files so they will no longer be tracked after
       the next commit.

       This only removes files from the current branch, not from the
       entire project history, and it does not delete them from the
       working directory.

       To undo a forget before the next commit, see hg add.

       Examples:

       • forget newly-added binary files:

         hg forget "set:added() and binary()"

       • forget files that would be excluded by .hgignore:

         hg forget "set:hgignore()"

       Returns 0 on success.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   graft
       hg graft [OPTION]... [-r] REV...

       This command uses Mercurial's merge logic to copy individual
       changes from other branches without merging branches in the
       history graph. This is sometimes known as 'backporting' or
       'cherry-picking'. By default, graft will copy user, date, and
       description from the source changesets.

       Changesets that are ancestors of the current revision, that have
       already been grafted, or that are merges will be skipped.

       If --log is specified, log messages will have a comment appended
       of the form:

       (grafted from CHANGESETHASH)

       If a graft merge results in conflicts, the graft process is
       interrupted so that the current merge can be manually resolved.
       Once all conflicts are addressed, the graft process can be
       continued with the -c/--continue option.

       Note   The -c/--continue option does not reapply earlier options.

       Examples:

       • copy a single change to the stable branch and edit its
         description:

         hg update stable
         hg graft --edit 9393

       • graft a range of changesets with one exception, updating dates:

         hg graft -D "2085::2093 and not 2091"

       • continue a graft after resolving conflicts:

         hg graft -c

       • show the source of a grafted changeset:

         hg log --debug -r tip

       Returns 0 on successful completion.

       Options:

       -r, --rev
              revisions to graft

       -c, --continue
              resume interrupted graft

       -e, --edit
              invoke editor on commit messages

       --log  append graft info to log message

       -D, --currentdate
              record the current date as commit date

       -U, --currentuser
              record the current user as committer

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

       -t, --tool
              specify merge tool

       -n, --dry-run
              do not perform actions, just print output

   grep
       hg grep [OPTION]... PATTERN [FILE]...

       Search revisions of files for a regular expression.

       This command behaves differently than Unix grep. It only accepts
       Python/Perl regexps. It searches repository history, not the
       working directory. It always prints the revision number in which
       a match appears.

       By default, grep only prints output for the first revision of a
       file in which it finds a match. To get it to print every revision
       that contains a change in match status ("-" for a match that
       becomes a non-match, or "+" for a non-match that becomes a
       match), use the --all flag.

       Returns 0 if a match is found, 1 otherwise.

       Options:

       -0, --print0
              end fields with NUL

       --all  print all revisions that match

       -a, --text
              treat all files as text

       -f, --follow
              follow changeset history, or file history across copies
              and renames

       -i, --ignore-case
              ignore case when matching

       -l, --files-with-matches
              print only filenames and revisions that match

       -n, --line-number
              print matching line numbers

       -r, --rev
              only search files changed within revision range

       -u, --user
              list the author (long with -v)

       -d, --date
              list the date (short with -q)

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   heads
       hg heads [-ct] [-r STARTREV] [REV]...

       With no arguments, show all repository branch heads.

       Repository "heads" are changesets with no child changesets. They
       are where development generally takes place and are the usual
       targets for update and merge operations. Branch heads are
       changesets that have no child changeset on the same branch.

       If one or more REVs are given, only branch heads on the branches
       associated with the specified changesets are shown. This means
       that you can use hg heads foo to see the heads on a branch named
       foo.

       If -c/--closed is specified, also show branch heads marked closed
       (see hg commit --close-branch).

       If STARTREV is specified, only those heads that are descendants
       of STARTREV will be displayed.

       If -t/--topo is specified, named branch mechanics will be ignored
       and only changesets without children will be shown.

       Returns 0 if matching heads are found, 1 if not.

       Options:

       -r, --rev
              show only heads which are descendants of STARTREV

       -t, --topo
              show topological heads only

       -a, --active
              show active branchheads only (DEPRECATED)

       -c, --closed
              show normal and closed branch heads

       --style
              display using template map file

       --template
              display with template

   help
       hg help [-ec] [TOPIC]

       With no arguments, print a list of commands with short help
       messages.

       Given a topic, extension, or command name, print help for that
       topic.

       Returns 0 if successful.

       Options:

       -e, --extension
              show only help for extensions

       -c, --command
              show only help for commands

       -k, --keyword
              show topics matching keyword

   identify
       hg identify [-nibtB] [-r REV] [SOURCE]

       Print a summary identifying the repository state at REV using one
       or two parent hash identifiers, followed by a "+" if the working
       directory has uncommitted changes, the branch name (if not
       default), a list of tags, and a list of bookmarks.

       When REV is not given, print a summary of the current state of
       the repository.

       Specifying a path to a repository root or Mercurial bundle will
       cause lookup to operate on that repository/bundle.

       Examples:

       • generate a build identifier for the working directory:

         hg id --id > build-id.dat

       • find the revision corresponding to a tag:

         hg id -n -r 1.3

       • check the most recent revision of a remote repository:

         hg id -r tip http://selenic.com/hg/

       Returns 0 if successful.

       Options:

       -r, --rev
              identify the specified revision

       -n, --num
              show local revision number

       -i, --id
              show global revision id

       -b, --branch
              show branch

       -t, --tags
              show tags

       -B, --bookmarks
              show bookmarks

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

              aliases: id

   import
       hg import [OPTION]... PATCH...

       Import a list of patches and commit them individually (unless
       --no-commit is specified).

       If there are outstanding changes in the working directory, import
       will abort unless given the -f/--force flag.

       You can import a patch straight from a mail message. Even patches
       as attachments work (to use the body part, it must have type
       text/plain or text/x-patch). From and Subject headers of email
       message are used as default committer and commit message. All
       text/plain body parts before first diff are added to commit
       message.

       If the imported patch was generated by hg export, user and
       description from patch override values from message headers and
       body. Values given on command line with -m/--message and
       -u/--user override these.

       If --exact is specified, import will set the working directory to
       the parent of each patch before applying it, and will abort if
       the resulting changeset has a different ID than the one recorded
       in the patch. This may happen due to character set problems or
       other deficiencies in the text patch format.

       Use --bypass to apply and commit patches directly to the
       repository, not touching the working directory. Without --exact,
       patches will be applied on top of the working directory parent
       revision.

       With -s/--similarity, hg will attempt to discover renames and
       copies in the patch in the same way as hg addremove.

       To read a patch from standard input, use "-" as the patch name.
       If a URL is specified, the patch will be downloaded from it.  See
       hg help dates for a list of formats valid for -d/--date.

       Examples:

       • import a traditional patch from a website and detect renames:

         hg import -s 80 http://example.com/bugfix.patch

       • import a changeset from an hgweb server:

         hg import http://www.selenic.com/hg/rev/5ca8c111e9aa

       • import all the patches in an Unix-style mbox:

         hg import incoming-patches.mbox

       • attempt to exactly restore an exported changeset (not always
         possible):

         hg import --exact proposed-fix.patch

       Returns 0 on success.

       Options:

       -p, --strip
              directory strip option for patch. This has the same
              meaning as the corresponding patch option (default: 1)

       -b, --base
              base path (DEPRECATED)

       -e, --edit
              invoke editor on commit messages

       -f, --force
              skip check for outstanding uncommitted changes

       --no-commit
              don't commit, just update the working directory

       --bypass
              apply patch without touching the working directory

       --exact
              apply patch to the nodes from which it was generated

       --import-branch
              use any branch information in patch (implied by --exact)

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

       -s, --similarity
              guess renamed files by similarity (0<=s<=100)

              aliases: patch

   incoming
       hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]

       Show new changesets found in the specified path/URL or the
       default pull location. These are the changesets that would have
       been pulled if a pull at the time you issued this command.

       For remote repository, using --bundle avoids downloading the
       changesets twice if the incoming is followed by a pull.

       See pull for valid source format details.

       Returns 0 if there are incoming changes, 1 otherwise.

       Options:

       -f, --force
              run even if remote repository is unrelated

       -n, --newest-first
              show newest record first

       --bundle
              file to store the bundles into

       -r, --rev
              a remote changeset intended to be added

       -B, --bookmarks
              compare bookmarks

       -b, --branch
              a specific branch you would like to pull

       -p, --patch
              show patch

       -g, --git
              use git extended diff format

       -l, --limit
              limit number of changes displayed

       -M, --no-merges
              do not show merges

       --stat output diffstat-style summary of changes

       -G, --graph
              show the revision DAG

       --style
              display using template map file

       --template
              display with template

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

       -S, --subrepos
              recurse into subrepositories

              aliases: in

   init
       hg init [-e CMD] [--remotecmd CMD] [DEST]

       Initialize a new repository in the given directory. If the given
       directory does not exist, it will be created.

       If no directory is given, the current directory is used.

       It is possible to specify an ssh:// URL as the destination.  See
       hg help urls for more information.

       Returns 0 on success.

       Options:

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

   locate
       hg locate [OPTION]... [PATTERN]...

       Print files under Mercurial control in the working directory
       whose names match the given patterns.

       By default, this command searches all directories in the working
       directory. To search just the current directory and its
       subdirectories, use "--include .".

       If no patterns are given to match, this command prints the names
       of all files under Mercurial control in the working directory.

       If you want to feed the output of this command into the "xargs"
       command, use the -0 option to both this command and "xargs". This
       will avoid the problem of "xargs" treating single filenames that
       contain whitespace as multiple filenames.

       Returns 0 if a match is found, 1 otherwise.

       Options:

       -r, --rev
              search the repository as it is in REV

       -0, --print0
              end filenames with NUL, for use with xargs

       -f, --fullpath
              print complete paths from the filesystem root

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   log
       hg log [OPTION]... [FILE]

       Print the revision history of the specified files or the entire
       project.

       If no revision range is specified, the default is tip:0 unless
       --follow is set, in which case the working directory parent is
       used as the starting revision.

       File history is shown without following rename or copy history of
       files. Use -f/--follow with a filename to follow history across
       renames and copies. --follow without a filename will only show
       ancestors or descendants of the starting revision.

       By default this command prints revision number and changeset id,
       tags, non-trivial parents, user, date and time, and a summary for
       each commit. When the -v/--verbose switch is used, the list of
       changed files and full commit message are shown.

       Note   log -p/--patch may generate unexpected diff output for
              merge changesets, as it will only compare the merge
              changeset against its first parent. Also, only files
              different from BOTH parents will appear in files:.

       Note   for performance reasons, log FILE may omit duplicate
              changes made on branches and will not show deletions. To
              see all changes including duplicates and deletions, use
              the --removed switch.

       Some examples:

       • changesets with full descriptions and file lists:

         hg log -v

       • changesets ancestral to the working directory:

         hg log -f

       • last 10 commits on the current branch:

         hg log -l 10 -b .

       • changesets showing all modifications of a file, including
         removals:

         hg log --removed file.c

       • all changesets that touch a directory, with diffs, excluding
         merges:

         hg log -Mp lib/

       • all revision numbers that match a keyword:

         hg log -k bug --template "{rev}\n"

       • check if a given changeset is included is a tagged release:

         hg log -r "a21ccf and ancestor(1.9)"

       • find all changesets by some user in a date range:

         hg log -k alice -d "may 2008 to jul 2008"

       • summary of all changesets after the last tag:

         hg log -r "last(tagged())::" --template "{desc|firstline}\n"

       See hg help dates for a list of formats valid for -d/--date.

       See hg help revisions and hg help revsets for more about
       specifying revisions.

       See hg help templates for more about pre-packaged styles and
       specifying custom templates.

       Returns 0 on success.

       Options:

       -f, --follow
              follow changeset history, or file history across copies
              and renames

       --follow-first

              show only merges (DEPRECATED)

       -u, --user
              revisions committed by user

       --only-branch
              show only changesets within the given named branch
              (DEPRECATED)

       -b, --branch
              show changesets within the given named branch

              aliases: history

   manifest
       hg manifest [-r REV]

       Print a list of version controlled files for the given revision.
       If no revision is given, the first parent of the working
       directory is used, or the null revision if no revision is checked
       out.

       With -v, print file permissions, symlink and executable bits.
       With --debug, print file revision hashes.

       If option --all is specified, the list of all files from all
       revisions is printed. This includes deleted and renamed files.

       Returns 0 on success.

       Options:

       -r, --rev
              revision to display

       --all  list files from all revisions

   merge
       hg merge [-P] [-f] [[-r] REV]

       The current working directory is updated with all changes made in
       the requested revision since the last common predecessor
       revision.

       Files that changed between either parent are marked as changed
       for the next commit and a commit must be performed before any
       further updates to the repository are allowed. The next commit
       will have two parents.

       --tool can be used to specify the merge tool used for file
       merges. It overrides the HGMERGE environment variable and your
       configuration files. See hg help merge-tools for options.

       If no revision is specified, the working directory's parent is a
       head revision, and the current branch contains exactly one other
       head, the other head is merged with by default. Otherwise, an
       explicit revision with which to merge with must be provided.

       hg resolve must be used to resolve unresolved files.

       To undo an uncommitted merge, use hg update --clean . which will
       check out a clean copy of the original merge parent, losing all
       changes.

       Returns 0 on success, 1 if there are unresolved files.

       Options:

       -f, --force
              force a merge with outstanding changes

       -r, --rev
              revision to merge

       -P, --preview
              review revisions to merge (no merge is performed)

       -t, --tool
              specify merge tool

   outgoing
       hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]

       Show changesets not found in the specified destination repository
       or the default push location. These are the changesets that would
       be pushed if a push was requested.

       See pull for details of valid destination formats.

       Returns 0 if there are outgoing changes, 1 otherwise.

       Options:

       -f, --force
              run even when the destination is unrelated

       -r, --rev
              a changeset intended to be included in the destination

       -n, --newest-first
              show newest record first

       -B, --bookmarks
              compare bookmarks

       -b, --branch

              limit number of changes displayed

       -M, --no-merges
              do not show merges

       --stat output diffstat-style summary of changes

       -G, --graph
              show the revision DAG

       --style
              display using template map file

       --template
              display with template

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

       -S, --subrepos
              recurse into subrepositories

              aliases: out

   parents
       hg parents [-r REV] [FILE]

       Print the working directory's parent revisions. If a revision is
       given via -r/--rev, the parent of that revision will be printed.
       If a file argument is given, the revision in which the file was
       last changed (before the working directory revision or the
       argument to --rev if given) is printed.

       Returns 0 on success.

       Options:

       -r, --rev
              show parents of the specified revision

       --style
              display using template map file

       --template
              display with template

   paths
       hg paths [NAME]

       Show definition of symbolic path name NAME. If no name is given,
       show definition of all available names.

       Option -q/--quiet suppresses all output when searching for NAME
       and shows only the path names when listing all definitions.

       Path names are defined in the [paths] section of your
       configuration file and in /etc/mercurial/hgrc. If run inside a
       repository, .hg/hgrc is used, too.

       The path names default and default-push have a special meaning.
       When performing a push or pull operation, they are used as
       fallbacks if no location is specified on the command-line.  When
       default-push is set, it will be used for push and default will be
       used for pull; otherwise default is used as the fallback for
       both.  When cloning a repository, the clone source is written as
       default in .hg/hgrc.  Note that default and default-push apply to
       all inbound (e.g.  hg incoming) and outbound (e.g. hg outgoing,
       hg email and hg bundle) operations.

       See hg help urls for more information.

       Returns 0 on success.

   phase
       hg phase [-p|-d|-s] [-f] [-r] REV...

       With no argument, show the phase name of specified revisions.

       With one of -p/--public, -d/--draft or -s/--secret, change the
       phase value of the specified revisions.

       Unless -f/--force is specified, hg phase won't move changeset
       from a lower phase to an higher phase. Phases are ordered as
       follows:

       public < draft < secret

       Return 0 on success, 1 if no phases were changed or some could
       not be changed.

       Options:

       -p, --public
              set changeset phase to public

       -d, --draft
              set changeset phase to draft

       -s, --secret
              set changeset phase to secret

       -f, --force
              allow to move boundary backward

       -r, --rev
              target revision

   pull
       hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]

       Pull changes from a remote repository to a local one.

       This finds all changes from the repository at the specified path
       or URL and adds them to a local repository (the current one
       unless -R is specified). By default, this does not update the
       copy of the project in the working directory.

       Use hg incoming if you want to see what would have been added by
       a pull at the time you issued this command. If you then decide to
       add those changes to the repository, you should use hg pull -r X
       where X is the last changeset listed by hg incoming.

       If SOURCE is omitted, the 'default' path will be used.  See hg
       help urls for more information.

       Returns 0 on success, 1 if an update had unresolved files.

       Options:

       -u, --update
              update to new branch head if changesets were pulled

       -f, --force
              run even when remote repository is unrelated

       -r, --rev
              a remote changeset intended to be added

       -B, --bookmark
              bookmark to pull

       -b, --branch
              a specific branch you would like to pull

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

   push
       hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]

       Push changesets from the local repository to the specified
       destination.

       This operation is symmetrical to pull: it is identical to a pull
       in the destination repository from the current one.

       By default, push will not allow creation of new heads at the
       destination, since multiple heads would make it unclear which
       head to use. In this situation, it is recommended to pull and
       merge before pushing.

       Use --new-branch if you want to allow push to create a new named
       branch that is not present at the destination. This allows you to
       only create a new branch without forcing other changes.

       Use -f/--force to override the default behavior and push all
       changesets on all branches.

       If -r/--rev is used, the specified revision and all its ancestors
       will be pushed to the remote repository.

       If -B/--bookmark is used, the specified bookmarked revision, its
       ancestors, and the bookmark will be pushed to the remote
       repository.

       Please see hg help urls for important details about ssh:// URLs.
       If DESTINATION is omitted, a default path will be used.

       Returns 0 if push was successful, 1 if nothing to push.

       Options:

       -f, --force
              force push

       -r, --rev
              a changeset intended to be included in the destination

       -B, --bookmark
              bookmark to push

       -b, --branch
              a specific branch you would like to push

       --new-branch
              allow pushing a new branch

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

   recover
       hg recover

       Recover from an interrupted commit or pull.

       This command tries to fix the repository status after an
       interrupted operation. It should only be necessary when Mercurial
       suggests it.

       Returns 0 if successful, 1 if nothing to recover or verify fails.

   remove
       hg remove [OPTION]... FILE...

       Schedule the indicated files for removal from the current branch.

       This command schedules the files to be removed at the next
       commit.  To undo a remove before that, see hg revert. To undo
       added files, see hg forget.

       -A/--after can be used to remove only files that have already
       been deleted, -f/--force can be used to force deletion, and -Af
       can be used to remove files from the next revision without
       deleting them from the working directory.

       The following table details the behavior of remove for different
       file states (columns) and option combinations (rows). The file
       states are Added [A], Clean [C], Modified [M] and Missing [!]
       (as reported by hg status). The actions are Warn, Remove (from
       branch) and Delete (from disk):

                           ┌─────┬───┬────┬────┬───┐
                           │     │   │    │    │   │
                           ├─────┼───┼────┼────┼───┤
                           │none │ W │ RD │ W  │ R │
                           ├─────┼───┼────┼────┼───┤
                           │-f   │ R │ RD │ RD │ R │

                           └─────┴───┴────┴────┴───┘

       Note that remove never deletes files in Added [A] state from the
       working directory, not even if option --force is specified.

       Returns 0 on success, 1 if any warnings encountered.

       Options:

       -A, --after
              record delete for missing files

       -f, --force
              remove (and delete) file even if added or modified

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

              aliases: rm

   rename
       hg rename [OPTION]... SOURCE... DEST

       Mark dest as copies of sources; mark sources for deletion. If
       dest is a directory, copies are put in that directory. If dest is
       a file, there can only be one source.

       By default, this command copies the contents of files as they
       exist in the working directory. If invoked with -A/--after, the
       operation is recorded, but no copying is performed.

       This command takes effect at the next commit. To undo a rename
       before that, see hg revert.

       Returns 0 on success, 1 if errors are encountered.

       Options:

       -A, --after
              record a rename that has already occurred

       -f, --force
              forcibly copy over an existing managed file

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -n, --dry-run
              do not perform actions, just print output

              aliases: move mv

   resolve
       hg resolve [OPTION]... [FILE]...

       Merges with unresolved conflicts are often the result of
       non-interactive merging using the internal:merge configuration
       setting, or a command-line merge tool like diff3. The resolve
       command is used to manage the files involved in a merge, after hg
       merge has been run, and before hg commit is run (i.e. the working
       directory must have two parents). See hg help merge-tools for
       information on configuring merge tools.

       The resolve command can be used in the following ways:

       • hg resolve [--tool TOOL] FILE...: attempt to re-merge the
         specified files, discarding any previous merge attempts.
         Re-merging is not performed for files already marked as
         resolved. Use --all/-a to select all unresolved files. --tool
         can be used to specify the merge tool used for the given files.
         It overrides the HGMERGE environment variable and your
         configuration files.  Previous file contents are saved with a
         .orig suffix.

       • hg resolve -m [FILE]: mark a file as having been resolved (e.g.
         after having manually fixed-up the files). The default is to
         mark all unresolved files.

       • hg resolve -u [FILE]...: mark a file as unresolved. The default
         is to mark all resolved files.

       • hg resolve -l: list files which had or still have conflicts.
         In the printed list, U = unresolved and R = resolved.

       Note that Mercurial will not let you commit files with unresolved
       merge conflicts. You must use hg resolve -m ... before you can
       commit after a conflicting merge.

       Returns 0 on success, 1 if any files fail a resolve attempt.

       Options:

       -a, --all
              select all unresolved files

       -l, --list
              list state of files needing merge

       -m, --mark
              mark files as resolved

       -u, --unmark
              mark files as unresolved

       -n, --no-status
              hide status prefix

       -t, --tool
              specify merge tool

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   revert
       hg revert [OPTION]... [-r REV] [NAME]...

       Note   To check out earlier revisions, you should use hg update
              REV.  To cancel an uncommitted merge (and lose your
              changes), use hg update --clean ..

       With no revision specified, revert the specified files or
       directories to the contents they had in the parent of the working
       directory.  This restores the contents of files to an unmodified
       state and unschedules adds, removes, copies, and renames. If the
       working directory has two parents, you must explicitly specify a
       revision.

       Using the -r/--rev or -d/--date options, revert the given files
       or directories to their states as of a specific revision. Because
       revert does not change the working directory parents, this will
       cause these files to appear modified. This can be helpful to
       "back out" some or all of an earlier change. See hg backout for a
       related method.

       Modified files are saved with a .orig suffix before reverting.
       To disable these backups, use --no-backup.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success.

       Options:

       -a, --all
              revert all changes when no arguments given

       -d, --date
              tipmost revision matching date

       -r, --rev
              revert to the specified revision

       -C, --no-backup
              do not save backup copies of files

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -n, --dry-run
              do not perform actions, just print output

   rollback
       hg rollback

       This command should be used with care. There is only one level of
       rollback, and there is no way to undo a rollback. It will also
       restore the dirstate at the time of the last transaction, losing
       any dirstate changes since that time. This command does not alter
       the working directory.

       Transactions are used to encapsulate the effects of all commands
       that create new changesets or propagate existing changesets into
       a repository.

       For example, the following commands are transactional, and their
       effects can be rolled back:

       • commit

       • import

       • pull

       • push (with this repository as the destination)

       • unbundle

       To avoid permanent data loss, rollback will refuse to rollback a
       commit transaction if it isn't checked out. Use --force to
       override this protection.

       This command is not intended for use on public repositories. Once
       changes are visible for pull by other users, rolling a
       transaction back locally is ineffective (someone else may already
       have pulled the changes). Furthermore, a race is possible with
       readers of the repository; for example an in-progress pull from
       the repository may fail if a rollback is performed.

       Returns 0 on success, 1 if no rollback data is available.

       Options:

       -n, --dry-run
              do not perform actions, just print output

       -f, --force
              ignore safety measures

   root
       hg root

       Print the root directory of the current repository.

       Returns 0 on success.

   serve
       hg serve [OPTION]...

       Start a local HTTP repository browser and pull server. You can
       use this for ad-hoc sharing and browsing of repositories. It is
       recommended to use a real web server to serve a repository for
       longer periods of time.

       Please note that the server does not implement access control.
       This means that, by default, anybody can read from the server and
       nobody can write to it by default. Set the web.allow_push option
       to * to allow everybody to push to the server. You should use a
       real web server if you need to authenticate users.

       By default, the server logs accesses to stdout and errors to
       stderr. Use the -A/--accesslog and -E/--errorlog options to log
       to files.

       To have the server choose a free port number to listen on,
       specify a port number of 0; in this case, the server will print
       the port number it uses.

       Returns 0 on success.

       Options:

       -A, --accesslog
              name of access log file to write to

       -d, --daemon
              run server in background

       --daemon-pipefds
              used internally by daemon mode

       -E, --errorlog
              name of error log file to write to

       -p, --port
              port to listen on (default: 8000)

       -a, --address
              address to listen on (default: all interfaces)

       --prefix
              prefix path to serve from (default: server root)

       -n, --name
              name to show in web pages (default: working directory)

       --web-conf
              name of the hgweb config file (see "hg help hgweb")

       --webdir-conf
              name of the hgweb config file (DEPRECATED)

       --pid-file
              name of file to write process ID to

       --stdio
              for remote clients

       --cmdserver
              for remote clients

       -t, --templates
              web templates to use

       --style
              template style to use

       -6, --ipv6
              use IPv6 in addition to IPv4

       --certificate
              SSL certificate file

   showconfig
       hg showconfig [-u] [NAME]...

       With no arguments, print names and values of all config items.

       With one argument of the form section.name, print just the value
       of that config item.

       With multiple arguments, print names and values of all config
       items with matching section names.

       With --debug, the source (filename and line number) is printed
       for each config item.

       Returns 0 on success.

       Options:

       -u, --untrusted
              show untrusted configuration options

              aliases: debugconfig

   status
       hg status [OPTION]... [FILE]...

       Show status of files in the repository. If names are given, only
       files that match are shown. Files that are clean or ignored or
       the source of a copy/move operation, are not listed unless
       -c/--clean, -i/--ignored, -C/--copies or -A/--all are given.
       Unless options described with "show only ..." are given, the
       options -mardu are used.

       Option -q/--quiet hides untracked (unknown and ignored) files
       unless explicitly requested with -u/--unknown or -i/--ignored.

       Note   status may appear to disagree with diff if permissions
              have changed or a merge has occurred. The standard diff
              format does not report permission changes and diff only
              reports changes relative to one merge parent.

       If one revision is given, it is used as the base revision.  If
       two revisions are given, the differences between them are shown.
       The --change option can also be used as a shortcut to list the
       changed files of a revision from its first parent.

       The codes used to show the status of files are:

       M = modified
       A = added
       R = removed
       C = clean
       ! = missing (deleted by non-hg command, but still tracked)
       ? = not tracked
       I = ignored
         = origin of the previous file listed as A (added)

       Examples:

       • show changes in the working directory relative to a changeset:

         hg status --rev 9353

       • show all changes including copies in an existing changeset:

         hg status --copies --change 9353

       • get a NUL separated list of added files, suitable for xargs:

         hg status -an0

       Returns 0 on success.

       Options:

       -A, --all
              show status of all files

       -m, --modified
              show only modified files

       -a, --added
              show only added files

       -r, --removed
              show only removed files

       -d, --deleted
              show only deleted (but tracked) files

       -c, --clean
              show only files without changes

       -u, --unknown
              show only unknown (not tracked) files

       -i, --ignored
              show only ignored files

       -n, --no-status
              hide status prefix

       -C, --copies
              show source of copied files

       -0, --print0
              end filenames with NUL, for use with xargs

       --rev  show difference from revision

       --change
              list the changed files of a revision

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -S, --subrepos
              recurse into subrepositories

              aliases: st

   summary
       hg summary [--remote]

       This generates a brief summary of the working directory state,
       including parents, branch, commit status, and available updates.

       With the --remote option, this will check the default paths for
       incoming and outgoing changes. This can be time-consuming.

       Returns 0 on success.

       Options:

       --remote
              check for push and pull

              aliases: sum

   tag
       hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...

       Name a particular revision using <name>.

       Tags are used to name particular revisions of the repository and
       are very useful to compare different revisions, to go back to
       significant earlier versions or to mark branch points as
       releases, etc. Changing an existing tag is normally disallowed;
       use -f/--force to override.

       If no revision is given, the parent of the working directory is
       used, or tip if no revision is checked out.

       To facilitate version control, distribution, and merging of tags,
       they are stored as a file named ".hgtags" which is managed
       similarly to other project files and can be hand-edited if
       necessary. This also means that tagging creates a new commit. The
       file ".hg/localtags" is used for local tags (not shared among
       repositories).

       Tag commits are usually made at the head of a branch. If the
       parent of the working directory is not a branch head, hg tag
       aborts; use -f/--force to force the tag commit to be based on a
       non-head changeset.

       See hg help dates for a list of formats valid for -d/--date.

       Since tag names have priority over branch names during revision
       lookup, using an existing branch name as a tag name is
       discouraged.

       Returns 0 on success.

       Options:

       -f, --force
              force tag

       -l, --local
              make the tag local

       -r, --rev
              revision to tag

       --remove
              remove a tag

       -e, --edit
              edit commit message

       -m, --message
              use <text> as commit message

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

   tags
       hg tags

       This lists both regular and local tags. When the -v/--verbose
       switch is used, a third column "local" is printed for local tags.

       Returns 0 on success.

   tip
       hg tip [-p] [-g]

       The tip revision (usually just called the tip) is the changeset
       most recently added to the repository (and therefore the most
       recently changed head).

       If you have just made a commit, that commit will be the tip. If
       you have just pulled changes from another repository, the tip of
       that repository becomes the current tip. The "tip" tag is special
       and cannot be renamed or assigned to a different changeset.

       Returns 0 on success.

       Options:

       -p, --patch
              show patch

       -g, --git
              use git extended diff format

       --style
              display using template map file

       --template
              display with template

   unbundle
       hg unbundle [-u] FILE...

       Apply one or more compressed changegroup files generated by the
       bundle command.

       Returns 0 on success, 1 if an update has unresolved files.

       Options:

       -u, --update
              update to new branch head if changesets were unbundled

   update
       hg update [-c] [-C] [-d DATE] [[-r] REV]

       Update the repository's working directory to the specified
       changeset. If no changeset is specified, update to the tip of the
       current named branch and move the current bookmark (see hg help
       bookmarks).

       Update sets the working directory's parent revision to the
       specified changeset (see hg help parents).

       If the changeset is not a descendant or ancestor of the working
       directory's parent, the update is aborted. With the -c/--check
       option, the working directory is checked for uncommitted changes;
       if none are found, the working directory is updated to the
       specified changeset.

       The following rules apply when the working directory contains
       uncommitted changes:

       1. If neither -c/--check nor -C/--clean is specified, and if the
          requested changeset is an ancestor or descendant of the
          working directory's parent, the uncommitted changes are merged
          into the requested changeset and the merged result is left
          uncommitted. If the requested changeset is not an ancestor or
          descendant (that is, it is on another branch), the update is
          aborted and the uncommitted changes are preserved.

       2. With the -c/--check option, the update is aborted and the
          uncommitted changes are preserved.

       3. With the -C/--clean option, uncommitted changes are discarded
          and the working directory is updated to the requested
          changeset.

       To cancel an uncommitted merge (and lose your changes), use hg
       update --clean ..

       Use null as the changeset to remove the working directory (like
       hg clone -U).

       If you want to revert just one file to an older revision, use hg
       revert [-r REV] NAME.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success, 1 if there are unresolved files.

       Options:

       -C, --clean
              discard uncommitted changes (no backup)

       -c, --check
              update across branches if no uncommitted changes

       -d, --date
              tipmost revision matching date

       -r, --rev
              revision

   verify
       hg verify

       Verify the integrity of the current repository.

       This will perform an extensive check of the repository's
       integrity, validating the hashes and checksums of each entry in
       the changelog, manifest, and tracked files, as well as the
       integrity of their crosslinks and indices.

DATE FORMATS         top

       Some commands allow the user to specify a date, e.g.:

       • backout, commit, import, tag: Specify the commit date.

       • log, revert, update: Select revision(s) by date.

       Many date formats are valid. Here are some examples:

       • Wed Dec 6 13:18:29 2006 (local timezone assumed)

       • Dec 6 13:18 -0600 (year assumed, time offset provided)

       • Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)

       • Dec 6 (midnight)

       • 13:18 (today assumed)

       • 3:39 (3:39AM assumed)

       • 3:39pm (15:39)

       • 2006-12-06 13:18:29 (ISO 8601 format)

       • 2006-12-6 13:182006-12-612-612/612/6/6 (Dec 6 2006)

       • today (midnight)

       • yesterday (midnight)

       • now - right now

       Lastly, there is Mercurial's internal format:

       • 1165432709 0 (Wed Dec 6 13:18:29 2006 UTC)

       This is the internal representation format for dates. The first
       number is the number of seconds since the epoch (1970-01-01 00:00
       UTC). The second is the offset of the local timezone, in seconds
       west of UTC (negative if the timezone is east of UTC).

       The log command also accepts date ranges:

       • <DATE - at or before a given date/time

       • >DATE - on or after a given date/time

       • DATE to DATE - a date range, inclusive

       • -DAYS - within a given number of days of today

DIFF FORMATS         top

       Mercurial's default format for showing changes between two
       versions of a file is compatible with the unified format of GNU
       diff, which can be used by GNU patch and many other standard
       tools.

       While this standard format is often enough, it does not encode
       the following information:

       • executable status and other permission bits

       • copy or rename information

       • changes in binary files

       • creation or deletion of empty files

       Mercurial also supports the extended diff format from the git VCS
       which addresses these limitations. The git diff format is not
       produced by default because a few widespread tools still do not
       understand this format.

       This means that when generating diffs from a Mercurial repository
       (e.g. with hg export), you should be careful about things like
       file copies and renames or other things mentioned above, because
       when applying a standard diff to a different repository, this
       extra information is lost. Mercurial's internal operations (like
       push and pull) are not affected by this, because they use an
       internal binary format for communicating changes.

       To make Mercurial produce the git extended diff format, use the
       --git option available for many commands, or set 'git = True' in
       the [diff] section of your configuration file. You do not need to
       set this option when importing diffs in this format or using them
       in the mq extension.

ENVIRONMENT VARIABLES         top

       HG     Path to the 'hg' executable, automatically passed when
              running hooks, extensions or external tools. If unset or
              empty, this is the hg executable's name if it's frozen, or
              an executable named 'hg' (with %PATHEXT% [defaulting to
              COM/EXE/BAT/CMD] extensions on Windows) is searched.

       HGEDITOR
              This is the name of the editor to run when committing. See
              EDITOR.

              (deprecated, use configuration file)

       HGENCODING
              This overrides the default locale setting detected by
              Mercurial.  This setting is used to convert data including
              usernames, changeset descriptions, tag names, and
              branches. This setting can be overridden with the
              --encoding command-line option.

       HGENCODINGMODE
              This sets Mercurial's behavior for handling unknown
              characters while transcoding user input. The default is
              "strict", which causes Mercurial to abort if it can't map
              a character. Other settings include "replace", which
              replaces unknown characters, and "ignore", which drops
              them. This setting can be overridden with the
              --encodingmode command-line option.

       HGENCODINGAMBIGUOUS
              This sets Mercurial's behavior for handling characters
              with "ambiguous" widths like accented Latin characters
              with East Asian fonts. By default, Mercurial assumes
              ambiguous characters are narrow, set this variable to
              "wide" if such characters cause formatting problems.

       HGMERGE
              An executable to use for resolving merge conflicts. The
              program will be executed with three arguments: local file,
              remote file, ancestor file.

              (deprecated, use configuration file)

       HGRCPATH
              A list of files or directories to search for configuration
              files. Item separator is ":" on Unix, ";" on Windows. If
              HGRCPATH is not set, platform default search path is used.
              If empty, only the .hg/hgrc from the current repository is
              read.

              For each element in HGRCPATH:

              • if it's a directory, all files ending with .rc are added

              • otherwise, the file itself will be added

       HGPLAIN
              When set, this disables any configuration settings that
              might change Mercurial's default output. This includes
              encoding, defaults, verbose mode, debug mode, quiet mode,
              tracebacks, and localization. This can be useful when
              scripting against Mercurial in the face of existing user
              configuration.

              Equivalent options set via command line flags or
              environment variables are not overridden.

       HGPLAINEXCEPT
              This is a comma-separated list of features to preserve
              when HGPLAIN is enabled. Currently the only value
              supported is "i18n", which preserves internationalization
              in plain mode.

              Setting HGPLAINEXCEPT to anything (even an empty string)
              will enable plain mode.

       HGUSER This is the string used as the author of a commit. If not
              set, available values will be considered in this order:

              • HGUSER (deprecated)

              • configuration files from the HGRCPATH

              • EMAIL

              • interactive prompt

              • LOGNAME (with @hostname appended)

              (deprecated, use configuration file)

       EMAIL  May be used as the author of a commit; see HGUSER.

       LOGNAME
              May be used as the author of a commit; see HGUSER.

       VISUAL This is the name of the editor to use when committing. See
              EDITOR.

       EDITOR Sometimes Mercurial needs to open a text file in an editor
              for a user to modify, for example when writing commit
              messages. The editor it uses is determined by looking at
              the environment variables HGEDITOR, VISUAL and EDITOR, in
              that order. The first non-empty one is chosen. If all of
              them are empty, the editor defaults to 'vi'.

       PYTHONPATH
              This is used by Python to find imported modules and may
              need to be set appropriately if this Mercurial is not
              installed system-wide.

USING ADDITIONAL FEATURES         top

       Mercurial has the ability to add new features through the use of
       extensions. Extensions may add new commands, add options to
       existing commands, change the default behavior of commands, or
       implement hooks.

       Extensions are not loaded by default for a variety of reasons:
       they can increase startup overhead; they may be meant for
       advanced usage only; they may provide potentially dangerous
       abilities (such as letting you destroy or modify history); they
       might not be ready for prime time; or they may alter some usual
       behaviors of stock Mercurial. It is thus up to the user to
       activate extensions as needed.

       To enable the "foo" extension, either shipped with Mercurial or
       in the Python search path, create an entry for it in your
       configuration file, like this:

       [extensions]
       foo =

       You may also specify the full path to an extension:

       [extensions]
       myfeature = ~/.hgext/myfeature.py

       To explicitly disable an extension enabled in a configuration
       file of broader scope, prepend its path with !:

       [extensions]
       # disabling extension bar residing in /path/to/extension/bar.py
       bar = !/path/to/extension/bar.py
       # ditto, but no path was supplied for extension baz
       baz = !

SPECIFYING FILE SETS         top

       Mercurial supports a functional language for selecting a set of
       files.

       Like other file patterns, this pattern type is indicated by a
       prefix, 'set:'. The language supports a number of predicates
       which are joined by infix operators. Parenthesis can be used for
       grouping.

       Identifiers such as filenames or patterns must be quoted with
       single or double quotes if they contain characters outside of
       [.*{}[]?/\_a-zA-Z0-9\x80-\xff] or if they match one of the
       predefined predicates. This generally applies to file patterns
       other than globs and arguments for predicates.

       Special characters can be used in quoted identifiers by escaping
       them, e.g., \n is interpreted as a newline. To prevent them from
       being interpreted, strings can be prefixed with r, e.g. r'...'.

       There is a single prefix operator:

       not x

              Files not in x. Short form is ! x.

       These are the supported infix operators:

       x and y

              The intersection of files in x and y. Short form is x & y.

       x or y

              The union of files in x and y. There are two alternative
              short forms: x | y and x + y.

       x - y

              Files in x but not in y.

       The following predicates are supported:

       added()

              File that is added according to status.

       binary()

              File that appears to be binary (contains NUL bytes).

       clean()

              File that is clean according to status.

       copied()

              File that is recorded as being copied.

       deleted()

              File that is deleted according to status.

       encoding(name)

              File can be successfully decoded with the given character
              encoding. May not be useful for encodings other than ASCII
              and UTF-8.

       eol(style)

              File contains newlines of the given style (dos, unix,
              mac). Binary files are excluded, files with mixed line
              endings match multiple styles.

       exec()

              File that is marked as executable.

       grep(regex)

              File contains the given regular expression.

       hgignore()

              File that matches the active .hgignore pattern.

       ignored()

              File that is ignored according to status. These files will
              only be considered if this predicate is used.

       modified()

              File that is modified according to status.

       removed()

              File that is removed according to status.

       resolved()

              File that is marked resolved according to the resolve
              state.

       size(expression)

              File size matches the given expression. Examples:

              • 1k (files from 1024 to 2047 bytes)

              • < 20k (files less than 20480 bytes)

              • >= .5MB (files at least 524288 bytes)

              • 4k - 1MB (files from 4096 bytes to 1048576 bytes)

       subrepo([pattern])

              Subrepositories whose paths match the given pattern.

       symlink()

              File that is marked as a symlink.

       unknown()

              File that is unknown according to status. These files will
              only be considered if this predicate is used.

       unresolved()

              File that is marked unresolved according to the resolve
              state.

       Some sample queries:

       • Show status of files that appear to be binary in the working
         directory:

         hg status -A "set:binary()"

       • Forget files that are in .hgignore but are already tracked:

         hg forget "set:hgignore() and not ignored()"

       • Find text files that contain a string:

         hg locate "set:grep(magic) and not binary()"

       • Find C files in a non-standard encoding:

         hg locate "set:**.c and not encoding('UTF-8')"

       • Revert copies of large binary files:

         hg revert "set:copied() and binary() and size('>1M')"

       • Remove files listed in foo.lst that contain the letter a or b:

         hg remove "set: 'listfile:foo.lst' and (**a* or **b*)"

       See also hg help patterns.

GLOSSARY         top

       Ancestor
              Any changeset that can be reached by an unbroken chain of
              parent changesets from a given changeset. More precisely,
              the ancestors of a changeset can be defined by two
              properties: a parent of a changeset is an ancestor, and a
              parent of an ancestor is an ancestor. See also:
              'Descendant'.

       Bookmark
              Bookmarks are pointers to certain commits that move when
              committing. They are similar to tags in that it is
              possible to use bookmark names in all places where
              Mercurial expects a changeset ID, e.g., with hg update.
              Unlike tags, bookmarks move along when you make a commit.

              Bookmarks can be renamed, copied and deleted. Bookmarks
              are local, unless they are explicitly pushed or pulled
              between repositories.  Pushing and pulling bookmarks allow
              you to collaborate with others on a branch without
              creating a named branch.

       Branch (Noun) A child changeset that has been created from a
              parent that is not a head. These are known as topological
              branches, see 'Branch, topological'. If a topological
              branch is named, it becomes a named branch. If a
              topological branch is not named, it becomes an anonymous
              branch. See 'Branch, anonymous' and 'Branch, named'.

              Branches may be created when changes are pulled from or
              pushed to a remote repository, since new heads may be
              created by these operations. Note that the term branch can
              also be used informally to describe a development process
              in which certain development is done independently of
              other development. This is sometimes done explicitly with
              a named branch, but it can also be done locally, using
              bookmarks or clones and anonymous branches.

              Example: "The experimental branch".

              (Verb) The action of creating a child changeset which
              results in its parent having more than one child.

              Example: "I'm going to branch at X".

       Branch, anonymous
              Every time a new child changeset is created from a parent
              that is not a head and the name of the branch is not
              changed, a new anonymous branch is created.

       Branch, closed
              A named branch whose branch heads have all been closed.

       Branch, default
              The branch assigned to a changeset when no name has
              previously been assigned.

       Branch head
              See 'Head, branch'.

       Branch, inactive
              If a named branch has no topological heads, it is
              considered to be inactive. As an example, a feature branch
              becomes inactive when it is merged into the default
              branch. The hg branches command shows inactive branches by
              default, though they can be hidden with hg branches
              --active.

              NOTE: this concept is deprecated because it is too
              implicit.  Branches should now be explicitly closed using
              hg commit --close-branch when they are no longer needed.

       Branch, named
              A collection of changesets which have the same branch
              name. By default, children of a changeset in a named
              branch belong to the same named branch. A child can be
              explicitly assigned to a different branch. See hg help
              branch, hg help branches and hg commit --close-branch for
              more information on managing branches.

              Named branches can be thought of as a kind of namespace,
              dividing the collection of changesets that comprise the
              repository into a collection of disjoint subsets. A named
              branch is not necessarily a topological branch. If a new
              named branch is created from the head of another named
              branch, or the default branch, but no further changesets
              are added to that previous branch, then that previous
              branch will be a branch in name only.

       Branch tip
              See 'Tip, branch'.

       Branch, topological
              Every time a new child changeset is created from a parent
              that is not a head, a new topological branch is created.
              If a topological branch is named, it becomes a named
              branch. If a topological branch is not named, it becomes
              an anonymous branch of the current, possibly default,
              branch.

       Changelog
              A record of the changesets in the order in which they were
              added to the repository. This includes details such as
              changeset id, author, commit message, date, and list of
              changed files.

       Changeset
              A snapshot of the state of the repository used to record a
              change.

       Changeset, child
              The converse of parent changeset: if P is a parent of C,
              then C is a child of P. There is no limit to the number of
              children that a changeset may have.

       Changeset id
              A SHA-1 hash that uniquely identifies a changeset. It may
              be represented as either a "long" 40 hexadecimal digit
              string, or a "short" 12 hexadecimal digit string.

       Changeset, merge
              A changeset with two parents. This occurs when a merge is
              committed.

       Changeset, parent
              A revision upon which a child changeset is based.
              Specifically, a parent changeset of a changeset C is a
              changeset whose node immediately precedes C in the DAG.
              Changesets have at most two parents.

       Checkout
              (Noun) The working directory being updated to a specific
              revision. This use should probably be avoided where
              possible, as changeset is much more appropriate than
              checkout in this context.

              Example: "I'm using checkout X."

              (Verb) Updating the working directory to a specific
              changeset. See hg help update.

              Example: "I'm going to check out changeset X."

       Child changeset
              See 'Changeset, child'.

       Close changeset
              See 'Head, closed branch'

       Closed branch
              See 'Branch, closed'.

       Clone  (Noun) An entire or partial copy of a repository. The
              partial clone must be in the form of a revision and its
              ancestors.

              Example: "Is your clone up to date?".

              (Verb) The process of creating a clone, using hg clone.

              Example: "I'm going to clone the repository".

       Closed branch head
              See 'Head, closed branch'.

       Commit (Noun) A synonym for changeset.

              Example: "Is the bug fixed in your recent commit?"

              (Verb) The act of recording changes to a repository. When
              files are committed in a working directory, Mercurial
              finds the differences between the committed files and
              their parent changeset, creating a new changeset in the
              repository.

              Example: "You should commit those changes now."

       Cset   A common abbreviation of the term changeset.

       DAG    The repository of changesets of a distributed version
              control system (DVCS) can be described as a directed
              acyclic graph (DAG), consisting of nodes and edges, where
              nodes correspond to changesets and edges imply a parent ->
              child relation. This graph can be visualized by graphical
              tools such as hg glog (graphlog). In Mercurial, the DAG is
              limited by the requirement for children to have at most
              two parents.

       Default branch
              See 'Branch, default'.

       Descendant
              Any changeset that can be reached by a chain of child
              changesets from a given changeset. More precisely, the
              descendants of a changeset can be defined by two
              properties: the child of a changeset is a descendant, and
              the child of a descendant is a descendant. See also:
              'Ancestor'.

       Diff   (Noun) The difference between the contents and attributes
              of files in two changesets or a changeset and the current
              working directory. The difference is usually represented
              in a standard form called a "diff" or "patch". The "git
              diff" format is used when the changes include copies,
              renames, or changes to file attributes, none of which can
              be represented/handled by classic "diff" and "patch".

              Example: "Did you see my correction in the diff?"

              (Verb) Diffing two changesets is the action of creating a
              diff or patch.

              Example: "If you diff with changeset X, you will see what
              I mean."

       Directory, working
              The working directory represents the state of the files
              tracked by Mercurial, that will be recorded in the next
              commit. The working directory initially corresponds to the
              snapshot at an existing changeset, known as the parent of
              the working directory. See 'Parent, working directory'.
              The state may be modified by changes to the files
              introduced manually or by a merge. The repository metadata
              exists in the .hg directory inside the working directory.

       Draft  Changesets in the draft phase have not been shared with
              publishing repositories and may thus be safely changed by
              history-modifying extensions. See hg help phases.

       Graph  See DAG and hg help graphlog.

       Head   The term 'head' may be used to refer to both a branch head
              or a repository head, depending on the context. See 'Head,
              branch' and 'Head, repository' for specific definitions.

              Heads are where development generally takes place and are
              the usual targets for update and merge operations.

       Head, branch
              A changeset with no descendants on the same named branch.

       Head, closed branch
              A changeset that marks a head as no longer interesting.
              The closed head is no longer listed by hg heads. A branch
              is considered closed when all its heads are closed and
              consequently is not listed by hg branches.

              Closed heads can be re-opened by committing new changeset
              as the child of the changeset that marks a head as closed.

       Head, repository
              A topological head which has not been closed.

       Head, topological
              A changeset with no children in the repository.

       History, immutable
              Once committed, changesets cannot be altered.  Extensions
              which appear to change history actually create new
              changesets that replace existing ones, and then destroy
              the old changesets. Doing so in public repositories can
              result in old changesets being reintroduced to the
              repository.

       History, rewriting
              The changesets in a repository are immutable. However,
              extensions to Mercurial can be used to alter the
              repository, usually in such a way as to preserve changeset
              contents.

       Immutable history
              See 'History, immutable'.

       Merge changeset
              See 'Changeset, merge'.

       Manifest
              Each changeset has a manifest, which is the list of files
              that are tracked by the changeset.

       Merge  Used to bring together divergent branches of work. When
              you update to a changeset and then merge another
              changeset, you bring the history of the latter changeset
              into your working directory. Once conflicts are resolved
              (and marked), this merge may be committed as a merge
              changeset, bringing two branches together in the DAG.

       Named branch
              See 'Branch, named'.

       Null changeset
              The empty changeset. It is the parent state of
              newly-initialized repositories and repositories with no
              checked out revision. It is thus the parent of root
              changesets and the effective ancestor when merging
              unrelated changesets. Can be specified by the alias 'null'
              or by the changeset ID '000000000000'.

       Parent See 'Changeset, parent'.

       Parent changeset
              See 'Changeset, parent'.

       Parent, working directory
              The working directory parent reflects a virtual revision
              which is the child of the changeset (or two changesets
              with an uncommitted merge) shown by hg parents. This is
              changed with hg update. Other commands to see the working
              directory parent are hg summary and hg id. Can be
              specified by the alias ".".

       Patch  (Noun) The product of a diff operation.

              Example: "I've sent you my patch."

              (Verb) The process of using a patch file to transform one
              changeset into another.

              Example: "You will need to patch that revision."

       Phase  A per-changeset state tracking how the changeset has been
              or should be shared. See hg help phases.

       Public Changesets in the public phase have been shared with
              publishing repositories and are therefore considered
              immutable. See hg help phases.

       Pull   An operation in which changesets in a remote repository
              which are not in the local repository are brought into the
              local repository. Note that this operation without special
              arguments only updates the repository, it does not update
              the files in the working directory. See hg help pull.

       Push   An operation in which changesets in a local repository
              which are not in a remote repository are sent to the
              remote repository. Note that this operation only adds
              changesets which have been committed locally to the remote
              repository. Uncommitted changes are not sent. See hg help
              push.

       Repository
              The metadata describing all recorded states of a
              collection of files. Each recorded state is represented by
              a changeset. A repository is usually (but not always)
              found in the .hg subdirectory of a working directory. Any
              recorded state can be recreated by "updating" a working
              directory to a specific changeset.

       Repository head
              See 'Head, repository'.

       Revision
              A state of the repository at some point in time. Earlier
              revisions can be updated to by using hg update.  See also
              'Revision number'; See also 'Changeset'.

       Revision number
              This integer uniquely identifies a changeset in a specific
              repository. It represents the order in which changesets
              were added to a repository, starting with revision number
              0. Note that the revision number may be different in each
              clone of a repository. To identify changesets uniquely
              between different clones, see 'Changeset id'.

       Revlog History storage mechanism used by Mercurial. It is a form
              of delta encoding, with occasional full revision of data
              followed by delta of each successive revision. It includes
              data and an index pointing to the data.

       Rewriting history
              See 'History, rewriting'.

       Root   A changeset that has only the null changeset as its
              parent. Most repositories have only a single root
              changeset.

       Secret Changesets in the secret phase may not be shared via push,
              pull, or clone. See hg help phases.

       Tag    An alternative name given to a changeset. Tags can be used
              in all places where Mercurial expects a changeset ID,
              e.g., with hg update. The creation of a tag is stored in
              the history and will thus automatically be shared with
              other using push and pull.

       Tip    The changeset with the highest revision number. It is the
              changeset most recently added in a repository.

       Tip, branch
              The head of a given branch with the highest revision
              number. When a branch name is used as a revision
              identifier, it refers to the branch tip. See also 'Branch,
              head'. Note that because revision numbers may be different
              in different repository clones, the branch tip may be
              different in different cloned repositories.

       Update (Noun) Another synonym of changeset.

              Example: "I've pushed an update".

              (Verb) This term is usually used to describe updating the
              state of the working directory to that of a specific
              changeset. See hg help update.

              Example: "You should update".

       Working directory
              See 'Directory, working'.

       Working directory parent
              See 'Parent, working directory'.

SYNTAX FOR MERCURIAL IGNORE FILES         top

   Synopsis
       The Mercurial system uses a file called .hgignore in the root
       directory of a repository to control its behavior when it
       searches for files that it is not currently tracking.

   Description
       The working directory of a Mercurial repository will often
       contain files that should not be tracked by Mercurial. These
       include backup files created by editors and build products
       created by compilers.  These files can be ignored by listing them
       in a .hgignore file in the root of the working directory. The
       .hgignore file must be created manually. It is typically put
       under version control, so that the settings will propagate to
       other repositories with push and pull.

       An untracked file is ignored if its path relative to the
       repository root directory, or any prefix path of that path, is
       matched against any pattern in .hgignore.

       For example, say we have an untracked file, file.c, at a/b/file.c
       inside our repository. Mercurial will ignore file.c if any
       pattern in .hgignore matches a/b/file.c, a/b or a.

       In addition, a Mercurial configuration file can reference a set
       of per-user or global ignore files. See the ignore configuration
       key on the [ui] section of hg help config for details of how to
       configure these files.

       To control Mercurial's handling of files that it manages, many
       commands support the -I and -X options; see hg help <command> and
       hg help patterns for details.

       Files that are already tracked are not affected by .hgignore,
       even if they appear in .hgignore. An untracked file X can be
       explicitly added with hg add X, even if X would be excluded by a
       pattern in .hgignore.

   Syntax
       An ignore file is a plain text file consisting of a list of
       patterns, with one pattern per line. Empty lines are skipped. The
       # character is treated as a comment character, and the \
       character is treated as an escape character.

       Mercurial supports several pattern syntaxes. The default syntax
       used is Python/Perl-style regular expressions.

       To change the syntax used, use a line of the following form:

       syntax: NAME

       where NAME is one of the following:

       regexp

              Regular expression, Python/Perl syntax.

       glob

              Shell-style glob.

       The chosen syntax stays in effect when parsing all patterns that
       follow, until another syntax is selected.

       Neither glob nor regexp patterns are rooted. A glob-syntax
       pattern of the form *.c will match a file ending in .c in any
       directory, and a regexp pattern of the form \.c$ will do the
       same. To root a regexp pattern, start it with ^.

       Note   Patterns specified in other than .hgignore are always
              rooted.  Please see hg help patterns for details.

   Example
       Here is an example ignore file.

       # use glob syntax.
       syntax: glob

       *.elc
       *.pyc
       *~

       # switch to regexp syntax.
       syntax: regexp
       ^\.pc/

CONFIGURING HGWEB         top

       Mercurial's internal web server, hgweb, can serve either a single
       repository, or a tree of repositories. In the second case,
       repository paths and global options can be defined using a
       dedicated configuration file common to hg serve, hgweb.wsgi,
       hgweb.cgi and hgweb.fcgi.

       This file uses the same syntax as other Mercurial configuration
       files but recognizes only the following sections:

          • web

          • paths

          • collections

       The web options are thoroughly described in hg help config.

       The paths section maps URL paths to paths of repositories in the
       filesystem. hgweb will not expose the filesystem directly - only
       Mercurial repositories can be published and only according to the
       configuration.

       The left hand side is the path in the URL. Note that hgweb
       reserves subpaths like rev or file, try using different names for
       nested repositories to avoid confusing effects.

       The right hand side is the path in the filesystem. If the
       specified path ends with * or ** the filesystem will be searched
       recursively for repositories below that point.  With * it will
       not recurse into the repositories it finds (except for
       .hg/patches).  With ** it will also search inside repository
       working directories and possibly find subrepositories.

       In this example:

       [paths]
       /projects/a = /srv/tmprepos/a
       /projects/b = c:/repos/b
       / = /srv/repos/*
       /user/bob = /home/bob/repos/**

       • The first two entries make two repositories in different
         directories appear under the same directory in the web
         interface

       • The third entry will publish every Mercurial repository found
         in /srv/repos/, for instance the repository /srv/repos/quux/
         will appear as http://server/quux/ 

       • The fourth entry will publish both http://server/user/bob/quux/ 
         and http://server/user/bob/quux/testsubrepo/ 

       The collections section is deprecated and has been superseded by
       paths.

MERGE TOOLS         top

       To merge files Mercurial uses merge tools.

       A merge tool combines two different versions of a file into a
       merged file. Merge tools are given the two files and the greatest
       common ancestor of the two file versions, so they can determine
       the changes made on both branches.

       Merge tools are used both for hg resolve, hg merge, hg update, hg
       backout and in several extensions.

       Usually, the merge tool tries to automatically reconcile the
       files by combining all non-overlapping changes that occurred
       separately in the two different evolutions of the same initial
       base file. Furthermore, some interactive merge programs make it
       easier to manually resolve conflicting merges, either in a
       graphical way, or by inserting some conflict markers. Mercurial
       does not include any interactive merge programs but relies on
       external tools for that.

   Available merge tools
       External merge tools and their properties are configured in the
       merge-tools configuration section - see hgrc(5) - but they can
       often just be named by their executable.

       A merge tool is generally usable if its executable can be found
       on the system and if it can handle the merge. The executable is
       found if it is an absolute or relative executable path or the
       name of an application in the executable search path. The tool is
       assumed to be able to handle the merge if it can handle symlinks
       if the file is a symlink, if it can handle binary files if the
       file is binary, and if a GUI is available if the tool requires a
       GUI.

       There are some internal merge tools which can be used. The
       internal merge tools are:

       internal:dump

              Creates three versions of the files to merge, containing
              the contents of local, other and base. These files can
              then be used to perform a merge manually. If the file to
              be merged is named a.txt, these files will accordingly be
              named a.txt.local, a.txt.other and a.txt.base and they
              will be placed in the same directory as a.txt.

       internal:fail

              Rather than attempting to merge files that were modified
              on both branches, it marks them as unresolved. The resolve
              command must be used to resolve these conflicts.

       internal:local

              Uses the local version of files as the merged version.

       internal:merge

              Uses the internal non-interactive simple merge algorithm
              for merging files. It will fail if there are any conflicts
              and leave markers in the partially merged file.

       internal:other

              Uses the other version of files as the merged version.

       internal:prompt

              Asks the user which of the local or the other version to
              keep as the merged version.

       Internal tools are always available and do not require a GUI but
       will by default not handle symlinks or binary files.

   Choosing a merge tool
       Mercurial uses these rules when deciding which merge tool to use:

       1. If a tool has been specified with the --tool option to merge
          or resolve, it is used.  If it is the name of a tool in the
          merge-tools configuration, its configuration is used.
          Otherwise the specified tool must be executable by the shell.

       2. If the HGMERGE environment variable is present, its value is
          used and must be executable by the shell.

       3. If the filename of the file to be merged matches any of the
          patterns in the merge-patterns configuration section, the
          first usable merge tool corresponding to a matching pattern is
          used. Here, binary capabilities of the merge tool are not
          considered.

       4. If ui.merge is set it will be considered next. If the value is
          not the name of a configured tool, the specified value is used
          and must be executable by the shell. Otherwise the named tool
          is used if it is usable.

       5. If any usable merge tools are present in the merge-tools
          configuration section, the one with the highest priority is
          used.

       6. If a program named hgmerge can be found on the system, it is
          used - but it will by default not be used for symlinks and
          binary files.

       7. If the file to be merged is not binary and is not a symlink,
          then internal:merge is used.

       8. The merge of the file fails and must be resolved before
          commit.

       Note   After selecting a merge program, Mercurial will by default
              attempt to merge the files using a simple merge algorithm
              first. Only if it doesn't succeed because of conflicting
              changes Mercurial will actually execute the merge program.
              Whether to use the simple merge algorithm first can be
              controlled by the premerge setting of the merge tool.
              Premerge is enabled by default unless the file is binary
              or a symlink.

       See the merge-tools and ui sections of hgrc(5) for details on the
       configuration of merge tools.

SPECIFYING MULTIPLE REVISIONS         top

       When Mercurial accepts more than one revision, they may be
       specified individually, or provided as a topologically continuous
       range, separated by the ":" character.

       The syntax of range notation is [BEGIN]:[END], where BEGIN and
       END are revision identifiers. Both BEGIN and END are optional. If
       BEGIN is not specified, it defaults to revision number 0. If END
       is not specified, it defaults to the tip. The range ":" thus
       means "all revisions".

       If BEGIN is greater than END, revisions are treated in reverse
       order.

       A range acts as a closed interval. This means that a range of 3:5
       gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.

FILE NAME PATTERNS         top

       Mercurial accepts several notations for identifying one or more
       files at a time.

       By default, Mercurial treats filenames as shell-style extended
       glob patterns.

       Alternate pattern notations must be specified explicitly.

       Note   Patterns specified in .hgignore are not rooted.  Please
              see hg help hgignore for details.

       To use a plain path name without any pattern matching, start it
       with path:. These path names must completely match starting at
       the current repository root.

       To use an extended glob, start a name with glob:. Globs are
       rooted at the current directory; a glob such as *.c will only
       match files in the current directory ending with .c.

       The supported glob syntax extensions are ** to match any string
       across path separators and {a,b} to mean "a or b".

       To use a Perl/Python regular expression, start a name with re:.
       Regexp pattern matching is anchored at the root of the
       repository.

       To read name patterns from a file, use listfile: or listfile0:.
       The latter expects null delimited patterns while the former
       expects line feeds. Each string read from the file is itself
       treated as a file pattern.

       Plain examples:

       path:foo/bar   a name bar in a directory named foo in the root
                      of the repository
       path:path:name a file or directory named "path:name"

       Glob examples:

       glob:*.c       any name ending in ".c" in the current directory
       *.c            any name ending in ".c" in the current directory
       **.c           any name ending in ".c" in any subdirectory of the
                      current directory including itself.
       foo/*.c        any name ending in ".c" in the directory foo
       foo/**.c       any name ending in ".c" in any subdirectory of foo
                      including itself.

       Regexp examples:

       re:.*\.c$      any name ending in ".c", anywhere in the repository

       File examples:

       listfile:list.txt  read list from list.txt with one file pattern per line
       listfile0:list.txt read list from list.txt with null byte delimiters

       See also hg help filesets.

WORKING WITH PHASES         top

   What are phases?
       Phases are a system for tracking which changesets have been or
       should be shared. This helps prevent common mistakes when
       modifying history (for instance, with the mq or rebase
       extensions).

       Each changeset in a repository is in one of the following phases:

          • public : changeset is visible on a public server

          • draft : changeset is not yet published

          • secret : changeset should not be pushed, pulled, or cloned

       These phases are ordered (public < draft < secret) and no
       changeset can be in a lower phase than its ancestors. For
       instance, if a changeset is public, all its ancestors are also
       public. Lastly, changeset phases should only be changed towards
       the public phase.

   How are phases managed?
       For the most part, phases should work transparently. By default,
       a changeset is created in the draft phase and is moved into the
       public phase when it is pushed to another repository.

       Once changesets become public, extensions like mq and rebase will
       refuse to operate on them to prevent creating duplicate
       changesets.  Phases can also be manually manipulated with the hg
       phase command if needed. See hg help -v phase for examples.

   Phases and servers
       Normally, all servers are publishing by default. This means:

       - all draft changesets that are pulled or cloned appear in phase
       public on the client

       - all draft changesets that are pushed appear as public on both
       client and server

       - secret changesets are neither pushed, pulled, or cloned

       Note   Pulling a draft changeset from a publishing server does
              not mark it as public on the server side due to the
              read-only nature of pull.

       Sometimes it may be desirable to push and pull changesets in the
       draft phase to share unfinished work. This can be done by setting
       a repository to disable publishing in its configuration file:

       [phases]
       publish = False

       See hg help config for more information on config files.

       Note   Servers running older versions of Mercurial are treated as
              publishing.

   Examples
          • list changesets in draft or secret phase:

            hg log -r "not public()"

          • change all secret changesets to draft:

            hg phase --draft "secret()"

          • forcibly move the current changeset and descendants from
            public to draft:

            hg phase --force --draft .

          • show a list of changeset revision and phase:

            hg log --template "{rev} {phase}\n"

          • resynchronize draft changesets relative to a remote
            repository:

            hg phase -fd 'outgoing(URL)'

       See hg help phase for more information on manually manipulating
       phases.

SPECIFYING SINGLE REVISIONS         top

       Mercurial supports several ways to specify individual revisions.

       A plain integer is treated as a revision number. Negative
       integers are treated as sequential offsets from the tip, with -1
       denoting the tip, -2 denoting the revision prior to the tip, and
       so forth.

       A 40-digit hexadecimal string is treated as a unique revision
       identifier.

       A hexadecimal string less than 40 characters long is treated as a
       unique revision identifier and is referred to as a short-form
       identifier. A short-form identifier is only valid if it is the
       prefix of exactly one full-length identifier.

       Any other string is treated as a bookmark, tag, or branch name. A
       bookmark is a movable pointer to a revision. A tag is a permanent
       name associated with a revision. A branch name denotes the
       tipmost revision of that branch. Bookmark, tag, and branch names
       must not contain the ":" character.

       The reserved name "tip" always identifies the most recent
       revision.

       The reserved name "null" indicates the null revision. This is the
       revision of an empty repository, and the parent of revision 0.

       The reserved name "." indicates the working directory parent. If
       no working directory is checked out, it is equivalent to null. If
       an uncommitted merge is in progress, "." is the revision of the
       first parent.

SPECIFYING REVISION SETS         top

       Mercurial supports a functional language for selecting a set of
       revisions.

       The language supports a number of predicates which are joined by
       infix operators. Parenthesis can be used for grouping.

       Identifiers such as branch names may need quoting with single or
       double quotes if they contain characters like - or if they match
       one of the predefined predicates.

       Special characters can be used in quoted identifiers by escaping
       them, e.g., \n is interpreted as a newline. To prevent them from
       being interpreted, strings can be prefixed with r, e.g. r'...'.

       There is a single prefix operator:

       not x

              Changesets not in x. Short form is ! x.

       These are the supported infix operators:

       x::y

              A DAG range, meaning all changesets that are descendants
              of x and ancestors of y, including x and y themselves. If
              the first endpoint is left out, this is equivalent to
              ancestors(y), if the second is left out it is equivalent
              to descendants(x).

              An alternative syntax is x..y.

       x:y

              All changesets with revision numbers between x and y, both
              inclusive. Either endpoint can be left out, they default
              to 0 and tip.

       x and y

              The intersection of changesets in x and y. Short form is x
              & y.

       x or y

              The union of changesets in x and y. There are two
              alternative short forms: x | y and x + y.

       x - y

              Changesets in x but not in y.

       x^n

              The nth parent of x, n == 0, 1, or 2.  For n == 0, x; for
              n == 1, the first parent of each changeset in x; for n ==
              2, the second parent of changeset in x.

       x~n

              The nth first ancestor of x; x~0 is x; x~3 is x^^^.

       There is a single postfix operator:

       x^

              Equivalent to x^1, the first parent of each changeset in
              x.

       The following predicates are supported:

       adds(pattern)

              Changesets that add a file matching pattern.

       all()

              All changesets, the same as 0:tip.

       ancestor(*changeset)

              Greatest common ancestor of the changesets.

              Accepts 0 or more changesets.  Will return empty list when
              passed no args.  Greatest common ancestor of a single
              changeset is that changeset.

       ancestors(set)

              Changesets that are ancestors of a changeset in set.

       author(string)

              Alias for user(string).

       bisect(string)

              Changesets marked in the specified bisect status:

              • good, bad, skip: csets explicitly marked as
                good/bad/skip

              • goods, bads      : csets topologically good/bad

              • range              : csets taking part in the bisection

              • pruned             : csets that are goods, bads or
                skipped

              • untested           : csets whose fate is yet unknown

              • ignored            : csets ignored due to DAG topology

              • current            : the cset currently being bisected

       bookmark([name])

              The named bookmark or all bookmarks.

              If name starts with re:, the remainder of the name is
              treated as a regular expression. To match a bookmark that
              actually starts with re:, use the prefix literal:.

       branch(string or set)

              All changesets belonging to the given branch or the
              branches of the given changesets.

              If string starts with re:, the remainder of the name is
              treated as a regular expression. To match a branch that
              actually starts with re:, use the prefix literal:.

       branchpoint()

              Changesets with more than one child.

       bumped()

              Mutable changesets marked as successors of public
              changesets.

              Only non-public and non-obsolete changesets can be bumped.

       bundle()

              Changesets in the bundle.

              Bundle must be specified by the -R option.

       children(set)

              Child changesets of changesets in set.

       closed()

              Changeset is closed.

       contains(pattern)

              Revision contains a file matching pattern. See hg help
              patterns for information about file patterns.

       converted([id])

              Changesets converted from the given identifier in the old
              repository if present, or all converted changesets if no
              identifier is specified.

       date(interval)

              Changesets within the interval, see hg help dates.

       desc(string)

              Search commit message for string. The match is
              case-insensitive.

       descendants(set)

              Changesets which are descendants of changesets in set.

       destination([set])

              Changesets that were created by a graft, transplant or
              rebase operation, with the given revisions specified as
              the source.  Omitting the optional set is the same as
              passing all().

       divergent()

              Final successors of changesets with an alternative set of
              final successors.

       draft()

              Changeset in draft phase.

       extinct()

              Obsolete changesets with obsolete descendants only.

       extra(label, [value])

              Changesets with the given label in the extra metadata,
              with the given optional value.

              If value starts with re:, the remainder of the value is
              treated as a regular expression. To match a value that
              actually starts with re:, use the prefix literal:.

       file(pattern)

              Changesets affecting files matched by pattern.

              For a faster but less accurate result, consider using
              filelog() instead.

       filelog(pattern)

              Changesets connected to the specified filelog.

              For performance reasons, filelog() does not show every
              changeset that affects the requested file(s). See hg help
              log for details. For a slower, more accurate result, use
              file().

       first(set, [n])

              An alias for limit().

       follow([file])

              An alias for ::. (ancestors of the working copy's first
              parent).  If a filename is specified, the history of the
              given file is followed, including copies.

       grep(regex)

              Like keyword(string) but accepts a regex. Use grep(r'...')
              to ensure special escape characters are handled correctly.
              Unlike keyword(string), the match is case-sensitive.

       head()

              Changeset is a named branch head.

       heads(set)

              Members of set with no children in set.

       hidden()

              Hidden changesets.

       id(string)

              Revision non-ambiguously specified by the given hex string
              prefix.

       keyword(string)

              Search commit message, user name, and names of changed
              files for string. The match is case-insensitive.

       last(set, [n])

              Last n members of set, defaulting to 1.

       limit(set, [n])

              First n members of set, defaulting to 1.

       matching(revision [, field])

              Changesets in which a given set of fields match the set of
              fields in the selected revision or set.

              To match more than one field pass the list of fields to
              match separated by spaces (e.g. author description).

              Valid fields are most regular revision fields and some
              special fields.

              Regular revision fields are description, author, branch,
              date, files, phase, parents, substate, user and diff.
              Note that author and user are synonyms. diff refers to the
              contents of the revision. Two revisions matching their
              diff will also match their files.

              Special fields are summary and metadata: summary matches
              the first line of the description.  metadata is equivalent
              to matching description user date (i.e. it matches the
              main metadata fields).

              metadata is the default field which is used when no fields
              are specified. You can match more than one field at a
              time.

       max(set)

              Changeset with highest revision number in set.

       merge()

              Changeset is a merge changeset.

       min(set)

              Changeset with lowest revision number in set.

       modifies(pattern)

              Changesets modifying files matched by pattern.

       obsolete()

              Mutable changeset with a newer version.

       origin([set])

              Changesets that were specified as a source for the grafts,
              transplants or rebases that created the given revisions.
              Omitting the optional set is the same as passing all().
              If a changeset created by these operations is itself
              specified as a source for one of these operations, only
              the source changeset for the first operation is selected.

       outgoing([path])

              Changesets not found in the specified destination
              repository, or the default push location.

       p1([set])

              First parent of changesets in set, or the working
              directory.

       p2([set])

              Second parent of changesets in set, or the working
              directory.

       parents([set])

              The set of all parents for all changesets in set, or the
              working directory.

       present(set)

              An empty set, if any revision in set isn't found;
              otherwise, all revisions in set.

              If any of specified revisions is not present in the local
              repository, the query is normally aborted. But this
              predicate allows the query to continue even in such cases.

       public()

              Changeset in public phase.

       remote([id [,path]])

              Local revision that corresponds to the given identifier in
              a remote repository, if present. Here, the '.' identifier
              is a synonym for the current local branch.

       removes(pattern)

              Changesets which remove files matching pattern.

       rev(number)

              Revision with the given numeric identifier.

       reverse(set)

              Reverse order of set.

       roots(set)

              Changesets in set with no parent changeset in set.

       secret()

              Changeset in secret phase.

       sort(set[, [-]key...])

              Sort set by keys. The default sort order is ascending,
              specify a key as -key to sort in descending order.

              The keys can be:

              • rev for the revision number,

              • branch for the branch name,

              • desc for the commit message (description),

              • user for user name (author can be used as an alias),

              • date for the commit date

       tag([name])

              The specified tag by name, or all tagged revisions if no
              name is given.

       unstable()

              Non-obsolete changesets with obsolete ancestors.

       user(string)

              User name contains string. The match is case-insensitive.

              If string starts with re:, the remainder of the string is
              treated as a regular expression. To match a user that
              actually contains re:, use the prefix literal:.

       New predicates (known as "aliases") can be defined, using any
       combination of existing predicates or other aliases. An alias
       definition looks like:

       <alias> = <definition>

       in the revsetalias section of a Mercurial configuration file.
       Arguments of the form $1, $2, etc. are substituted from the alias
       into the definition.

       For example,

       [revsetalias]
       h = heads()
       d($1) = sort($1, date)
       rs($1, $2) = reverse(sort($1, $2))

       defines three aliases, h, d, and rs. rs(0:tip, author) is exactly
       equivalent to reverse(sort(0:tip, author)).

       Command line equivalents for hg log:

       -f    ->  ::.
       -d x  ->  date(x)
       -k x  ->  keyword(x)
       -m    ->  merge()
       -u x  ->  user(x)
       -b x  ->  branch(x)
       -P x  ->  !::x
       -l x  ->  limit(expr, x)

       Some sample queries:

       • Changesets on the default branch:

         hg log -r "branch(default)"

       • Changesets on the default branch since tag 1.5 (excluding
         merges):

         hg log -r "branch(default) and 1.5:: and not merge()"

       • Open branch heads:

         hg log -r "head() and not closed()"

       • Changesets between tags 1.3 and 1.5 mentioning "bug" that
         affect hgext/*:

         hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"

       • Changesets committed in May 2008, sorted by user:

         hg log -r "sort(date('May 2008'), user)"

       • Changesets mentioning "bug" or "issue" that are not in a tagged
         release:

         hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tag())"

SUBREPOSITORIES         top

       Subrepositories let you nest external repositories or projects
       into a parent Mercurial repository, and make commands operate on
       them as a group.

       Mercurial currently supports Mercurial, Git, and Subversion
       subrepositories.

       Subrepositories are made of three components:

       1. Nested repository checkouts. They can appear anywhere in the
          parent working directory.

       2. Nested repository references. They are defined in .hgsub,
          which should be placed in the root of working directory, and
          tell where the subrepository checkouts come from. Mercurial
          subrepositories are referenced like:

          path/to/nested = https://example.com/nested/repo/path

          Git and Subversion subrepos are also supported:

          path/to/nested = [git]git://example.com/nested/repo/path
          path/to/nested = [svn]https://example.com/nested/trunk/path

          where path/to/nested is the checkout location relatively to
          the parent Mercurial root, and
          https://example.com/nested/repo/path is the source repository
          path. The source can also reference a filesystem path.

          Note that .hgsub does not exist by default in Mercurial
          repositories, you have to create and add it to the parent
          repository before using subrepositories.

       3. Nested repository states. They are defined in .hgsubstate,
          which is placed in the root of working directory, and capture
          whatever information is required to restore the
          subrepositories to the state they were committed in a parent
          repository changeset. Mercurial automatically record the
          nested repositories states when committing in the parent
          repository.

       Note
          The .hgsubstate file should not be edited manually.

   Adding a Subrepository
       If .hgsub does not exist, create it and add it to the parent
       repository. Clone or checkout the external projects where you
       want it to live in the parent repository. Edit .hgsub and add the
       subrepository entry as described above. At this point, the
       subrepository is tracked and the next commit will record its
       state in .hgsubstate and bind it to the committed changeset.

   Synchronizing a Subrepository
       Subrepos do not automatically track the latest changeset of their
       sources. Instead, they are updated to the changeset that
       corresponds with the changeset checked out in the top-level
       changeset. This is so developers always get a consistent set of
       compatible code and libraries when they update.

       Thus, updating subrepos is a manual process. Simply check out
       target subrepo at the desired revision, test in the top-level
       repo, then commit in the parent repository to record the new
       combination.

   Deleting a Subrepository
       To remove a subrepository from the parent repository, delete its
       reference from .hgsub, then remove its files.

   Interaction with Mercurial Commands
       add    add does not recurse in subrepos unless -S/--subrepos is
              specified.  However, if you specify the full path of a
              file in a subrepo, it will be added even without
              -S/--subrepos specified.  Git and Subversion
              subrepositories are currently silently ignored.

       archive
              archive does not recurse in subrepositories unless
              -S/--subrepos is specified.

       commit commit creates a consistent snapshot of the state of the
              entire project and its subrepositories. If any
              subrepositories have been modified, Mercurial will abort.
              Mercurial can be made to instead commit all modified
              subrepositories by specifying -S/--subrepos, or setting
              "ui.commitsubrepos=True" in a configuration file (see hg
              help config).  After there are no longer any modified
              subrepositories, it records their state and finally
              commits it in the parent repository.

       diff   diff does not recurse in subrepos unless -S/--subrepos is
              specified. Changes are displayed as usual, on the
              subrepositories elements. Git and Subversion
              subrepositories are currently silently ignored.

       forget forget currently only handles exact file matches in
              subrepos.  Git and Subversion subrepositories are
              currently silently ignored.

       incoming
              incoming does not recurse in subrepos unless -S/--subrepos
              is specified. Git and Subversion subrepositories are
              currently silently ignored.

       outgoing
              outgoing does not recurse in subrepos unless -S/--subrepos
              is specified. Git and Subversion subrepositories are
              currently silently ignored.

       pull   pull is not recursive since it is not clear what to pull
              prior to running hg update. Listing and retrieving all
              subrepositories changes referenced by the parent
              repository pulled changesets is expensive at best,
              impossible in the Subversion case.

       push   Mercurial will automatically push all subrepositories
              first when the parent repository is being pushed. This
              ensures new subrepository changes are available when
              referenced by top-level repositories.  Push is a no-op for
              Subversion subrepositories.

       status status does not recurse into subrepositories unless
              -S/--subrepos is specified. Subrepository changes are
              displayed as regular Mercurial changes on the
              subrepository elements. Subversion subrepositories are
              currently silently ignored.

       update update restores the subrepos in the state they were
              originally committed in target changeset. If the recorded
              changeset is not available in the current subrepository,
              Mercurial will pull it in first before updating.  This
              means that updating can require network access when using
              subrepositories.

   Remapping Subrepositories Sources
       A subrepository source location may change during a project life,
       invalidating references stored in the parent repository history.
       To fix this, rewriting rules can be defined in parent repository
       hgrc file or in Mercurial configuration. See the [subpaths]
       section in hgrc(5) for more details.

TEMPLATE USAGE         top

       Mercurial allows you to customize output of commands through
       templates. You can either pass in a template from the command
       line, via the --template option, or select an existing
       template-style (--style).

       You can customize output for any "log-like" command: log,
       outgoing, incoming, tip, parents, heads and glog.

       Five styles are packaged with Mercurial: default (the style used
       when no explicit preference is passed), compact, changelog,
       phases and xml.  Usage:

       $ hg log -r1 --style changelog

       A template is a piece of text, with markup to invoke variable
       expansion:

       $ hg log -r1 --template "{node}\n"
       b56ce7b07c52de7d5fd79fb89701ea538af65746

       Strings in curly braces are called keywords. The availability of
       keywords depends on the exact context of the templater. These
       keywords are usually available for templating a log-like command:

       author String. The unmodified author of the changeset.

       bisect String. The changeset bisection status.

       bookmarks
              List of strings. Any bookmarks associated with the
              changeset.

       branch String. The name of the branch on which the changeset was
              committed.

       branches
              List of strings. The name of the branch on which the
              changeset was committed. Will be empty if the branch name
              was default.

       children
              List of strings. The children of the changeset.

              "modified files: +added/-removed lines"

       file_adds
              List of strings. Files added by this changeset.

       file_copies
              List of strings. Files copied in this changeset with their
              sources.

       file_copies_switch
              List of strings. Like "file_copies" but displayed only if
              the --copied switch is set.

       file_dels
              List of strings. Files removed by this changeset.

       file_mods
              List of strings. Files modified by this changeset.

       files  List of strings. All files modified, added, or removed by
              this changeset.

       latesttag
              String. Most recent global tag in the ancestors of this
              changeset.

       latesttagdistance
              Integer. Longest path to the latest tag.

       node   String. The changeset identification hash, as a 40
              hexadecimal digit string.

       p1node String. The identification hash of the changeset's first
              parent, as a 40 digit hexadecimal string. If the changeset
              has no parents, all digits are 0.

       p1rev  Integer. The repository-local revision number of the
              changeset's first parent, or -1 if the changeset has no
              parents.

       p2node String. The identification hash of the changeset's second
              parent, as a 40 digit hexadecimal string. If the changeset
              has no second parent, all digits are 0.

       p2rev  Integer. The repository-local revision number of the
              changeset's second parent, or -1 if the changeset has no
              second parent.

       parents
              List of strings. The parents of the changeset in
              "rev:node" format. If the changeset has only one "natural"
              parent (the predecessor revision) nothing is shown.

       phase  String. The changeset phase name.

       phaseidx
              Integer. The changeset phase index.

       rev    Integer. The repository-local changeset revision number.

       tags   List of strings. Any tags associated with the changeset.

       The "date" keyword does not produce human-readable output. If you
       want to use a date in your output, you can use a filter to
       process it. Filters are functions which return a string based on
       the input variable. Be sure to use the stringify filter first
       when you're applying a string-input filter to a list-like input
       variable.  You can also use a chain of filters to get the desired
       output:

       $ hg tip --template "{date|isodate}\n"
       2008-08-21 18:22 +0000

       List of filters:

       email  Any text. Extracts the first string that looks like an
              email address. Example: User <user@example.com> becomes
              user@example.com.

              XML entities.

       person Any text. Returns the name before an email address,
              interpreting it as per RFC 5322.

       rfc3339date
              Date. Returns a date using the Internet date format

              Date. Returns a date using the same format used in email
              headers: "Tue, 18 Aug 2009 13:00:13 +0200".

       short  Changeset hash. Returns the short form of a changeset
              hash, i.e. a 12 hexadecimal digit string.

       shortbisect
              Any text. Treats text as a bisection status, and returns a
              single-character representing the status (G: good, B: bad,
              S: skipped, U: untested, I: ignored). Returns single space
              if text is not a valid bisection status.

       shortdate
              Date. Returns a date like "2006-09-18".

       stringify
              Any type. Turns the value into text by converting values
              into text and concatenating them.

       strip  Any text. Strips all leading and trailing whitespace.

       stripdir
              Treat the text as path and strip a directory level, if
              possible. For example, "foo" and "foo/bar" becomes "foo".

       tabindent
              Any text. Returns the text, with every line except the
              first starting with a tab character.

       urlescape
              Any text. Escapes all "special" characters. For example,
              "foo bar" becomes "foo%20bar".

       user   Any text. Returns a short representation of a user name or
              email address.

       Note that a filter is nothing more than a function call, i.e.
       expr|filter is equivalent to filter(expr).

       In addition to filters, there are some basic built-in functions:

       • date(date[, fmt])

       • fill(text[, width])

       • get(dict, key)

       • if(expr, then[, else])

       • ifeq(expr, expr, then[, else])

       • join(list, sep)

       • label(label, expr)

       • sub(pat, repl, expr)

       • rstdoc(text, style)

       Also, for any expression that returns a list, there is a list
       operator:

       • expr % "{template}"

       Some sample command line templates:

       • Format lists, e.g. files:

         $ hg log -r 0 --template "files:\n{files % '  {file}\n'}"

       • Join the list of files with a ", ":

         $ hg log -r 0 --template "files: {join(files, ', ')}\n"

       • Format date:

         $ hg log -r 0 --template "{date(date, '%Y')}\n"

       • Output the description set to a fill-width of 30:

         $ hg log -r 0 --template "{fill(desc, '30')}"

       • Use a conditional to test for the default branch:

         $ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch',
         'on branch {branch}')}\n"

       • Append a newline if not empty:

         $ hg tip --template "{if(author, '{author}\n')}"

       • Label the output for use with the color extension:

         $ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n"

       • Invert the firstline filter, i.e. everything but the first
         line:

         $ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n"

URL PATHS         top

       Valid URLs are of the form:

       local/filesystem/path[#revision]
       file://local/filesystem/path[#revision]
       http://[user[:pass]@]host[:port]/[path][#revision]
       https://[user[:pass]@]host[:port]/[path][#revision]
       ssh://[user@]host[:port]/[path][#revision]

       Paths in the local filesystem can either point to Mercurial
       repositories or to bundle files (as created by hg bundle or :hg:`
       incoming --bundle`). See also hg help paths.

       An optional identifier after # indicates a particular branch,
       tag, or changeset to use from the remote repository. See also hg
       help revisions.

       Some features, such as pushing to http:// and https:// URLs are
       only possible if the feature is explicitly enabled on the remote
       Mercurial server.

       Note that the security of HTTPS URLs depends on proper
       configuration of web.cacerts.

       Some notes about using SSH with Mercurial:

       • SSH requires an accessible shell account on the destination
         machine and a copy of hg in the remote path or specified with
         as remotecmd.

       • path is relative to the remote user's home directory by
         default. Use an extra slash at the start of a path to specify
         an absolute path:

         ssh://example.com//tmp/repository

       • Mercurial doesn't use its own compression via SSH; the right
         thing to do is to configure it in your ~/.ssh/config, e.g.:

         Host *.mylocalnetwork.example.com
           Compression no
         Host *
           Compression yes

         Alternatively specify "ssh -C" as your ssh command in your
         configuration file or with the --ssh command line option.

       These URLs can all be stored in your configuration file with path
       aliases under the [paths] section like so:

       [paths]
       alias1 = URL1
       alias2 = URL2
       ...

       You can then use the alias for any command that uses a URL (for
       example hg pull alias1 will be treated as hg pull URL1).

       Two path aliases are special because they are used as defaults
       when you do not provide the URL to a command:

       default:
              When you create a repository with hg clone, the clone
              command saves the location of the source repository as the
              new repository's 'default' path. This is then used when
              you omit path from push- and pull-like commands (including
              incoming and outgoing).

       default-push:
              The push command will look for a path named
              'default-push', and prefer it over 'default' if both are
              defined.

EXTENSIONS         top

       This section contains help for extensions that are distributed
       together with Mercurial. Help for other extensions is available
       in the help system.

   acl
       hooks for controlling repository access

       This hook makes it possible to allow or deny write access to
       given branches and paths of a repository when receiving incoming
       changesets via pretxnchangegroup and pretxncommit.

       The authorization is matched based on the local user name on the
       system where the hook runs, and not the committer of the original
       changeset (since the latter is merely informative).

       The acl hook is best used along with a restricted shell like
       hgsh, preventing authenticating users from doing anything other
       than pushing or pulling. The hook is not safe to use if users
       have interactive shell access, as they can then disable the hook.
       Nor is it safe if remote users share an account, because then
       there is no way to distinguish them.

       The order in which access checks are performed is:

       1. Deny  list for branches (section acl.deny.branches)

       2. Allow list for branches (section acl.allow.branches)

       3. Deny  list for paths    (section acl.deny)

       4. Allow list for paths    (section acl.allow)

       The allow and deny sections take key-value pairs.

   Branch-based Access Control
       Use the acl.deny.branches and acl.allow.branches sections to have
       branch-based access control. Keys in these sections can be
       either:

       • a branch name, or

       • an asterisk, to match any branch;

       The corresponding values can be either:

       • a comma-separated list containing users and groups, or

       • an asterisk, to match anyone;

       You can add the "!" prefix to a user or group name to invert the
       sense of the match.

   Path-based Access Control
       Use the acl.deny and acl.allow sections to have path-based access
       control. Keys in these sections accept a subtree pattern (with a
       glob syntax by default). The corresponding values follow the same
       syntax as the other sections above.

   Groups
       Group names must be prefixed with an @ symbol. Specifying a group
       name has the same effect as specifying all the users in that
       group.

       You can define group members in the acl.groups section.  If a
       group name is not defined there, and Mercurial is running under a
       Unix-like system, the list of users will be taken from the OS.
       Otherwise, an exception will be raised.

   Example Configuration
       [hooks]

       # Use this if you want to check access restrictions at commit time
       pretxncommit.acl = python:hgext.acl.hook

       # Use this if you want to check access restrictions for pull, push,
       # bundle and serve.
       pretxnchangegroup.acl = python:hgext.acl.hook

       [acl]
       # Allow or deny access for incoming changes only if their source is
       # listed here, let them pass otherwise. Source is "serve" for all
       # remote access (http or ssh), "push", "pull" or "bundle" when the
       # related commands are run locally.
       # Default: serve
       sources = serve

       [acl.deny.branches]

       # Everyone is denied to the frozen branch:
       frozen-branch = *

       # A bad user is denied on all branches:
       * = bad-user

       [acl.allow.branches]

       # A few users are allowed on branch-a:
       branch-a = user-1, user-2, user-3

       # Only one user is allowed on branch-b:
       branch-b = user-1

       # The super user is allowed on any branch:
       * = super-user

       # Everyone is allowed on branch-for-tests:
       branch-for-tests = *

       [acl.deny]
       # This list is checked first. If a match is found, acl.allow is not
       # checked. All users are granted access if acl.deny is not present.
       # Format for both lists: glob pattern = user, ..., @group, ...

       # To match everyone, use an asterisk for the user:
       # my/glob/pattern = *

       # user6 will not have write access to any file:
       ** = user6

       # Group "hg-denied" will not have write access to any file:
       ** = @hg-denied

       # Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
       # everyone being able to change all other files. See below.
       src/main/resources/DONT-TOUCH-THIS.txt = *

       [acl.allow]
       # if acl.allow is not present, all users are allowed by default
       # empty acl.allow = no users allowed

       # User "doc_writer" has write access to any file under the "docs"
       # folder:
       docs/** = doc_writer

       # User "jack" and group "designers" have write access to any file
       # under the "images" folder:
       images/** = jack, @designers

       # Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
       # will have write access to any file under the "resources" folder
       # (except for 1 file. See acl.deny):
       src/main/resources/** = *

       .hgtags = release_engineer

   Examples using the ! prefix
       Suppose there's a branch that only a given user (or group) should
       be able to push to, and you don't want to restrict access to any
       other branch that may be created.

       The "!" prefix allows you to prevent anyone except a given user
       or group to push changesets in a given branch or path.

       In the examples below, we will: 1) Deny access to branch "ring"
       to anyone but user "gollum" 2) Deny access to branch "lake" to
       anyone but members of the group "hobbit" 3) Deny access to a file
       to anyone but user "gollum"

       [acl.allow.branches]
       # Empty

       [acl.deny.branches]

       # 1) only 'gollum' can commit to branch 'ring';
       # 'gollum' and anyone else can still commit to any other branch.
       ring = !gollum

       # 2) only members of the group 'hobbit' can commit to branch 'lake';
       # 'hobbit' members and anyone else can still commit to any other branch.
       lake = !@hobbit

       # You can also deny access based on file paths:

       [acl.allow]
       # Empty

       [acl.deny]
       # 3) only 'gollum' can change the file below;
       # 'gollum' and anyone else can still change any other file.
       /misty/mountains/cave/ring = !gollum

   blackbox
       log repository events to a blackbox for debugging

       Logs event information to .hg/blackbox.log to help debug and
       diagnose problems.  The events that get logged can be configured
       via the blackbox.track config key.  Examples:

       [blackbox]
       track = *

       [blackbox]
       track = command, commandfinish, commandexception, exthook, pythonhook

       [blackbox]
       track = incoming

       [blackbox]
       # limit the size of a log file
       maxsize = 1.5 MB
       # rotate up to N log files when the current one gets too big
       maxfiles = 3

   Commands
   blackbox
       hg blackbox [OPTION]...

       view the recent repository events

       Options:

       -l, --limit
              the number of events to show (default: 10)

   bugzilla
       hooks for integrating with the Bugzilla bug tracker

       This hook extension adds comments on bugs in Bugzilla when
       changesets that refer to bugs by Bugzilla ID are seen. The
       comment is formatted using the Mercurial template mechanism.

       The bug references can optionally include an update for Bugzilla
       of the hours spent working on the bug. Bugs can also be marked
       fixed.

       Three basic modes of access to Bugzilla are provided:

       1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla
          3.4 or later.

       2. Check data via the Bugzilla XMLRPC interface and submit bug
          change via email to Bugzilla email interface. Requires
          Bugzilla 3.4 or later.

       3. Writing directly to the Bugzilla database. Only Bugzilla
          installations using MySQL are supported. Requires Python
          MySQLdb.

       Writing directly to the database is susceptible to schema
       changes, and relies on a Bugzilla contrib script to send out bug
       change notification emails. This script runs as the user running
       Mercurial, must be run on the host with the Bugzilla install, and
       requires permission to read Bugzilla configuration details and
       the necessary MySQL user and password to have full access rights
       to the Bugzilla database. For these reasons this access mode is
       now considered deprecated, and will not be updated for new
       Bugzilla versions going forward. Only adding comments is
       supported in this access mode.

       Access via XMLRPC needs a Bugzilla username and password to be
       specified in the configuration. Comments are added under that
       username. Since the configuration must be readable by all
       Mercurial users, it is recommended that the rights of that user
       are restricted in Bugzilla to the minimum necessary to add
       comments. Marking bugs fixed requires Bugzilla 4.0 and later.

       Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends
       email to the Bugzilla email interface to submit comments to bugs.
       The From: address in the email is set to the email address of the
       Mercurial user, so the comment appears to come from the Mercurial
       user. In the event that the Mercurial user email is not
       recognized by Bugzilla as a Bugzilla user, the email associated
       with the Bugzilla username used to log into Bugzilla is used
       instead as the source of the comment. Marking bugs fixed works on
       all supported Bugzilla versions.

       Configuration items common to all access modes:

       bugzilla.version
              The access type to use. Values recognized are:

              xmlrpc

                     Bugzilla XMLRPC interface.

              xmlrpc+email

                     Bugzilla XMLRPC and email interfaces.

              3.0

                     MySQL access, Bugzilla 3.0 and later.

              2.18

                     MySQL access, Bugzilla 2.18 and up to but not
                     including 3.0.

              2.16

                     MySQL access, Bugzilla 2.16 and up to but not
                     including 2.18.

       bugzilla.regexp
              Regular expression to match bug IDs for update in
              changeset commit message.  It must contain one "()" named
              group <ids> containing the bug IDs separated by non-digit
              characters. It may also contain a named group <hours> with
              a floating-point number giving the hours worked on the
              bug. If no named groups are present, the first "()" group
              is assumed to contain the bug IDs, and work time is not
              updated. The default expression matches Bug 1234, Bug no.
              1234, Bug number 1234, Bugs 1234,5678, Bug 1234 and 5678
              and variations thereof, followed by an hours number
              prefixed by h or hours, e.g. hours 1.5. Matching is case
              insensitive.

       bugzilla.fixregexp
              Regular expression to match bug IDs for marking fixed in
              changeset commit message. This must contain a "()" named
              group <ids>` containing the bug IDs separated by non-digit
              characters. It may also contain a named group ``<hours>
              with a floating-point number giving the hours worked on
              the bug. If no named groups are present, the first "()"
              group is assumed to contain the bug IDs, and work time is
              not updated. The default expression matches Fixes 1234,
              Fixes bug 1234, Fixes bugs 1234,5678, Fixes 1234 and 5678
              and variations thereof, followed by an hours number
              prefixed by h or hours, e.g. hours 1.5. Matching is case
              insensitive.

       bugzilla.fixstatus
              The status to set a bug to when marking fixed. Default
              RESOLVED.

       bugzilla.fixresolution
              The resolution to set a bug to when marking fixed. Default
              FIXED.

       bugzilla.style
              The style file to use when formatting comments.

       bugzilla.template
              Template to use when formatting comments. Overrides style
              if specified. In addition to the usual Mercurial keywords,
              the extension specifies:

              {bug}

                     The Bugzilla bug ID.

              {root}

                     The full pathname of the Mercurial repository.

              {webroot}

                     Stripped pathname of the Mercurial repository.

              {hgweb}

                     Base URL for browsing Mercurial repositories.

              Default changeset {node|short} in repo {root} refers to
              bug {bug}.\ndetails:\n\t{desc|tabindent}

       bugzilla.strip
              The number of path separator characters to strip from the
              front of the Mercurial repository path ({root} in
              templates) to produce {webroot}. For example, a repository
              with {root} /var/local/my-project with a strip of 2 gives
              a value for {webroot} of my-project. Default 0.

       web.baseurl
              Base URL for browsing Mercurial repositories. Referenced
              from templates as {hgweb}.

       Configuration items common to XMLRPC+email and MySQL access
       modes:

       bugzilla.usermap
              Path of file containing Mercurial committer email to
              Bugzilla user email mappings. If specified, the file
              should contain one mapping per line:

              committer = Bugzilla user

              See also the [usermap] section.

       The [usermap] section is used to specify mappings of Mercurial
       committer email to Bugzilla user email. See also
       bugzilla.usermap.  Contains entries of the form committer =
       Bugzilla user.

       XMLRPC access mode configuration:

       bugzilla.bzurl
              The base URL for the Bugzilla installation.  Default
              http://localhost/bugzilla .

       bugzilla.user
              The username to use to log into Bugzilla via XMLRPC.
              Default bugs.

       bugzilla.password
              The password for Bugzilla login.

       XMLRPC+email access mode uses the XMLRPC access mode
       configuration items, and also:

       bugzilla.bzemail
              The Bugzilla email address.

       In addition, the Mercurial email settings must be configured. See
       the documentation in hgrc(5), sections [email] and [smtp].

       MySQL access mode configuration:

       bugzilla.host
              Hostname of the MySQL server holding the Bugzilla
              database.  Default localhost.

       bugzilla.db
              Name of the Bugzilla database in MySQL. Default bugs.

       bugzilla.user
              Username to use to access MySQL server. Default bugs.

       bugzilla.password
              Password to use to access MySQL server.

       bugzilla.timeout
              Database connection timeout (seconds). Default 5.

       bugzilla.bzuser
              Fallback Bugzilla user name to record comments with, if
              changeset committer cannot be found as a Bugzilla user.

       bugzilla.bzdir
              Bugzilla install directory. Used by default notify.
              Default /var/www/html/bugzilla.

       bugzilla.notify
              The command to run to get Bugzilla to send bug change
              notification emails. Substitutes from a map with 3 keys,
              bzdir, id (bug id) and user (committer bugzilla email).

   children
       command to display child changesets (DEPRECATED)

       This extension is deprecated. You should use hg log -r
       "children(REV)" instead.

   Commands
   children
       hg children [-r REV] [FILE]

       Print the children of the working directory's revisions. If a
       revision is given via -r/--rev, the children of that revision
       will be printed. If a file argument is given, revision in which
       the file was last changed (after the working directory revision
       or the argument to --rev if given) is printed.

       Options:

       -r, --rev
              show children of the specified revision

       --style
              display using template map file

       --template
              display with template

   churn
       command to display statistics about repository history

   Commands
   churn
       hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]

       This command will display a histogram representing the number of
       changed lines or revisions, grouped according to the given
       template. The default template will group changes by author.  The
       --dateformat option may be used to group the results by date
       instead.

       Statistics are based on the number of changed lines, or
       alternatively the number of matching revisions if the
       --changesets option is specified.

       Examples:

       # display count of changed lines for every committer
       hg churn -t '{author|email}'

       # display daily activity graph
       hg churn -f '%H' -s -c

       # display activity of developers by month
       hg churn -f '%Y-%m' -s -c

       # display count of lines changed in every year
       hg churn -f '%Y' -s

       It is possible to map alternate email addresses to a main address
       by providing a file using the following format:

       <alias email> = <actual email>

       Such a file may be specified with the --aliases option, otherwise
       a .hgchurn file will be looked for in the working directory root.

       Options:

       -r, --rev
              count rate for the specified revision or range

       -d, --date
              count rate for revisions matching date spec

       -t, --template
              template to group changesets (default: {author|email})

       -f, --dateformat
              strftime-compatible format for grouping by date

       -c, --changesets
              count rate by number of changesets

       -s, --sort
              sort by key (default: sort by count)

       --diffstat
              display added/removed lines separately

       --aliases
              file with email aliases

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   color
       colorize output from some commands

       This extension modifies the status and resolve commands to add
       color to their output to reflect file status, the qseries command
       to add color to reflect patch status (applied, unapplied,
       missing), and to diff-related commands to highlight additions,
       removals, diff headers, and trailing whitespace.

       Other effects in addition to color, like bold and underlined
       text, are also available. By default, the terminfo database is
       used to find the terminal codes used to change color and effect.
       If terminfo is not available, then effects are rendered with the
       ECMA-48 SGR control function (aka ANSI escape codes).

       Default effects may be overridden from your configuration file:

       [color]
       status.modified = blue bold underline red_background
       status.added = green bold
       status.removed = red bold blue_background
       status.deleted = cyan bold underline
       status.unknown = magenta bold underline
       status.ignored = black bold

       # 'none' turns off all effects
       status.clean = none
       status.copied = none

       qseries.applied = blue bold underline
       qseries.unapplied = black bold
       qseries.missing = red bold

       diff.diffline = bold
       diff.extended = cyan bold
       diff.file_a = red bold
       diff.file_b = green bold
       diff.hunk = magenta
       diff.deleted = red
       diff.inserted = green
       diff.changed = white
       diff.trailingwhitespace = bold red_background

       resolve.unresolved = red bold
       resolve.resolved = green bold

       bookmarks.current = green

       branches.active = none
       branches.closed = black bold
       branches.current = green
       branches.inactive = none

       tags.normal = green
       tags.local = black bold

       The available effects in terminfo mode are 'blink', 'bold',
       'dim', 'inverse', 'invisible', 'italic', 'standout', and
       'underline'; in ECMA-48 mode, the options are 'bold', 'inverse',
       'italic', and 'underline'.  How each is rendered depends on the
       terminal emulator.  Some may not be available for a given
       terminal type, and will be silently ignored.

       Note that on some systems, terminfo mode may cause problems when
       using color with the pager extension and less -R. less with the
       -R option will only display ECMA-48 color codes, and terminfo
       mode may sometimes emit codes that less doesn't understand. You
       can work around this by either using ansi mode (or auto mode), or
       by using less -r (which will pass through all terminal control
       codes, not just color control codes).

       Because there are only eight standard colors, this module allows
       you to define color names for other color slots which might be
       available for your terminal type, assuming terminfo mode.  For
       instance:

       color.brightblue = 12
       color.pink = 207
       color.orange = 202

       to set 'brightblue' to color slot 12 (useful for 16 color
       terminals that have brighter colors defined in the upper eight)
       and, 'pink' and 'orange' to colors in 256-color xterm's default
       color cube.  These defined colors may then be used as any of the
       pre-defined eight, including appending '_background' to set the
       background to that color.

       By default, the color extension will use ANSI mode (or win32 mode
       on Windows) if it detects a terminal. To override auto mode (to
       enable terminfo mode, for example), set the following
       configuration option:

       [color]
       mode = terminfo

       Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will
       disable color.

   convert
       import revisions from foreign VCS repositories into Mercurial

   Commands
   convert
       hg convert [OPTION]... SOURCE [DEST [REVMAP]]

       Accepted source formats [identifiers]:

       • Mercurial [hg]

       • CVS [cvs]

       • Darcs [darcs]

       • git [git]

       • Subversion [svn]

       • Monotone [mtn]

       • GNU Arch [gnuarch]

       • Bazaar [bzr]

       • Perforce [p4]

       Accepted destination formats [identifiers]:

       • Mercurial [hg]

       • Subversion [svn] (history on branches is not preserved)

       If no revision is given, all revisions will be converted.
       Otherwise, convert will only import up to the named revision
       (given in a format understood by the source).

       If no destination directory name is specified, it defaults to the
       basename of the source with -hg appended. If the destination
       repository doesn't exist, it will be created.

       By default, all sources except Mercurial will use --branchsort.
       Mercurial uses --sourcesort to preserve original revision numbers
       order. Sort modes have the following effects:

       --branchsort
              convert from parent to child revision when possible, which
              means branches are usually converted one after the other.
              It generates more compact repositories.

       --datesort
              sort revisions by date. Converted repositories have
              good-looking changelogs but are often an order of
              magnitude larger than the same ones generated by
              --branchsort.

       --sourcesort
              try to preserve source revisions order, only supported by
              Mercurial sources.

       --closesort
              try to move closed revisions as close as possible to
              parent branches, only supported by Mercurial sources.

       If REVMAP isn't given, it will be put in a default location
       (<dest>/.hg/shamap by default). The REVMAP is a simple text file
       that maps each source commit ID to the destination ID for that
       revision, like so:

       <source ID> <destination ID>

       If the file doesn't exist, it's automatically created. It's
       updated on each commit copied, so hg convert can be interrupted
       and can be run repeatedly to copy new commits.

       The authormap is a simple text file that maps each source commit
       author to a destination commit author. It is handy for source
       SCMs that use unix logins to identify authors (e.g.: CVS). One
       line per author mapping and the line format is:

       source author = destination author

       Empty lines and lines starting with a # are ignored.

       The filemap is a file that allows filtering and remapping of
       files and directories. Each line can contain one of the following
       directives:

       include path/to/file-or-dir

       exclude path/to/file-or-dir

       rename path/to/source path/to/destination

       Comment lines start with #. A specified path matches if it equals
       the full relative name of a file or one of its parent
       directories. The include or exclude directive with the longest
       matching path applies, so line order does not matter.

       The include directive causes a file, or all files under a
       directory, to be included in the destination repository, and the
       exclusion of all other files and directories not explicitly
       included. The exclude directive causes files or directories to be
       omitted. The rename directive renames a file or directory if it
       is converted. To rename from a subdirectory into the root of the
       repository, use . as the path to rename to.

       The splicemap is a file that allows insertion of synthetic
       history, letting you specify the parents of a revision. This is
       useful if you want to e.g. give a Subversion merge two parents,
       or graft two disconnected series of history together. Each entry
       contains a key, followed by a space, followed by one or two
       comma-separated values:

       key parent1, parent2

       The key is the revision ID in the source revision control system
       whose parents should be modified (same format as a key in
       .hg/shamap). The values are the revision IDs (in either the
       source or destination revision control system) that should be
       used as the new parents for that node. For example, if you have
       merged "release-1.0" into "trunk", then you should specify the
       revision on "trunk" as the first parent and the one on the
       "release-1.0" branch as the second.

       The branchmap is a file that allows you to rename a branch when
       it is being brought in from whatever external repository. When
       used in conjunction with a splicemap, it allows for a powerful
       combination to help fix even the most badly mismanaged
       repositories and turn them into nicely structured Mercurial
       repositories. The branchmap contains lines of the form:

       original_branch_name new_branch_name

       where "original_branch_name" is the name of the branch in the
       source repository, and "new_branch_name" is the name of the
       branch is the destination repository. No whitespace is allowed in
       the branch names. This can be used to (for instance) move code in
       one repository from "default" to a named branch.

   Mercurial Source
       The Mercurial source recognizes the following configuration
       options, which you can set on the command line with --config:

       convert.hg.ignoreerrors
              ignore integrity errors when reading.  Use it to fix
              Mercurial repositories with missing revlogs, by converting
              from and to Mercurial. Default is False.

       convert.hg.saverev
              store original revision ID in changeset (forces target IDs
              to change). It takes a boolean argument and defaults to
              False.

       convert.hg.startrev
              convert start revision and its descendants.  It takes a hg
              revision identifier and defaults to 0.

   CVS Source
       CVS source will use a sandbox (i.e. a checked-out copy) from CVS
       to indicate the starting point of what will be converted. Direct
       access to the repository files is not needed, unless of course
       the repository is :local:. The conversion uses the top level
       directory in the sandbox to find the CVS repository, and then
       uses CVS rlog commands to find files to convert. This means that
       unless a filemap is given, all files under the starting directory
       will be converted, and that any directory reorganization in the
       CVS sandbox is ignored.

       The following options can be used with --config:

       convert.cvsps.cache
              Set to False to disable remote log caching, for testing
              and debugging purposes. Default is True.

       convert.cvsps.fuzz
              Specify the maximum time (in seconds) that is allowed
              between commits with identical user and log message in a
              single changeset. When very large files were checked in as
              part of a changeset then the default may not be long
              enough.  The default is 60.

       convert.cvsps.mergeto
              Specify a regular expression to which commit log messages
              are matched. If a match occurs, then the conversion
              process will insert a dummy revision merging the branch on
              which this log message occurs to the branch indicated in
              the regex. Default is {{mergetobranch ([-\w]+)}}

       convert.cvsps.mergefrom
              Specify a regular expression to which commit log messages
              are matched. If a match occurs, then the conversion
              process will add the most recent revision on the branch
              indicated in the regex as the second parent of the
              changeset. Default is {{mergefrombranch ([-\w]+)}}

       convert.localtimezone
              use local time (as determined by the TZ environment
              variable) for changeset date/times. The default is False
              (use UTC).

       hooks.cvslog
              Specify a Python function to be called at the end of
              gathering the CVS log. The function is passed a list with
              the log entries, and can modify the entries in-place, or
              add or delete them.

       hooks.cvschangesets
              Specify a Python function to be called after the
              changesets are calculated from the CVS log. The function
              is passed a list with the changeset entries, and can
              modify the changesets in-place, or add or delete them.

       An additional "debugcvsps" Mercurial command allows the builtin
       changeset merging code to be run without doing a conversion. Its
       parameters and output are similar to that of cvsps 2.1. Please
       see the command help for more details.

   Subversion Source
       Subversion source detects classical trunk/branches/tags layouts.
       By default, the supplied svn://repo/path/ source URL is converted
       as a single branch. If svn://repo/path/trunk exists it replaces
       the default branch. If svn://repo/path/branches exists, its
       subdirectories are listed as possible branches. If
       svn://repo/path/tags exists, it is looked for tags referencing
       converted branches. Default trunk, branches and tags values can
       be overridden with following options. Set them to paths relative
       to the source URL, or leave them blank to disable auto detection.

       The following options can be set with --config:

       convert.svn.branches
              specify the directory containing branches.  The default is
              branches.

       convert.svn.tags
              specify the directory containing tags. The default is
              tags.

       convert.svn.trunk
              specify the name of the trunk branch. The default is
              trunk.

       convert.localtimezone
              use local time (as determined by the TZ environment
              variable) for changeset date/times. The default is False
              (use UTC).

       Source history can be retrieved starting at a specific revision,
       instead of being integrally converted. Only single branch
       conversions are supported.

       convert.svn.startrev
              specify start Subversion revision number.  The default is
              0.

   Perforce Source
       The Perforce (P4) importer can be given a p4 depot path or a
       client specification as source. It will convert all files in the
       source to a flat Mercurial repository, ignoring labels, branches
       and integrations. Note that when a depot path is given you then
       usually should specify a target directory, because otherwise the
       target may be named ...-hg.

       It is possible to limit the amount of source history to be
       converted by specifying an initial Perforce revision:

       convert.p4.startrev
              specify initial Perforce revision (a Perforce changelist
              number).

   Mercurial Destination
       The following options are supported:

       convert.hg.clonebranches
              dispatch source branches in separate clones. The default
              is False.

       convert.hg.tagsbranch
              branch name for tag revisions, defaults to default.

       convert.hg.usebranchnames
              preserve branch names. The default is True.

       Options:

       --authors
              username mapping filename (DEPRECATED, use --authormap
              instead)

       -s, --source-type
              source repository type

       -d, --dest-type
              destination repository type

              try to reorder closed revisions

   eol
       automatically manage newlines in repository files

       This extension allows you to manage the type of line endings
       (CRLF or LF) that are used in the repository and in the local
       working directory. That way you can get CRLF line endings on
       Windows and LF on Unix/Mac, thereby letting everybody use their
       OS native line endings.

       The extension reads its configuration from a versioned .hgeol
       configuration file found in the root of the working copy. The
       .hgeol file use the same syntax as all other Mercurial
       configuration files. It uses two sections, [patterns] and
       [repository].

       The [patterns] section specifies how line endings should be
       converted between the working copy and the repository. The format
       is specified by a file pattern. The first match is used, so put
       more specific patterns first. The available line endings are LF,
       CRLF, and BIN.

       Files with the declared format of CRLF or LF are always checked
       out and stored in the repository in that format and files
       declared to be binary (BIN) are left unchanged. Additionally,
       native is an alias for checking out in the platform's default
       line ending: LF on Unix (including Mac OS X) and CRLF on Windows.
       Note that BIN (do nothing to line endings) is Mercurial's default
       behaviour; it is only needed if you need to override a later,
       more general pattern.

       The optional [repository] section specifies the line endings to
       use for files stored in the repository. It has a single setting,
       native, which determines the storage line endings for files
       declared as native in the [patterns] section. It can be set to LF
       or CRLF. The default is LF. For example, this means that on
       Windows, files configured as native (CRLF by default) will be
       converted to LF when stored in the repository. Files declared as
       LF, CRLF, or BIN in the [patterns] section are always stored
       as-is in the repository.

       Example versioned .hgeol file:

       [patterns]
       **.py = native
       **.vcproj = CRLF
       **.txt = native
       Makefile = LF
       **.jpg = BIN

       [repository]
       native = LF

       Note   The rules will first apply when files are touched in the
              working copy, e.g. by updating to null and back to tip to
              touch all files.

       The extension uses an optional [eol] section read from both the
       normal Mercurial configuration files and the .hgeol file, with
       the latter overriding the former. You can use that section to
       control the overall behavior. There are three settings:

       • eol.native (default os.linesep) can be set to LF or CRLF to
         override the default interpretation of native for checkout.
         This can be used with hg archive on Unix, say, to generate an
         archive where files have line endings for Windows.

       • eol.only-consistent (default True) can be set to False to make
         the extension convert files with inconsistent EOLs.
         Inconsistent means that there is both CRLF and LF present in
         the file.  Such files are normally not touched under the
         assumption that they have mixed EOLs on purpose.

       • eol.fix-trailing-newline (default False) can be set to True to
         ensure that converted files end with a EOL character (either \n
         or \r\n as per the configured patterns).

       The extension provides cleverencode: and cleverdecode: filters
       like the deprecated win32text extension does. This means that you
       can disable win32text and enable eol and your filters will still
       work. You only need to these filters until you have prepared a
       .hgeol file.

       The win32text.forbid* hooks provided by the win32text extension
       have been unified into a single hook named eol.checkheadshook.
       The hook will lookup the expected line endings from the .hgeol
       file, which means you must migrate to a .hgeol file first before
       using the hook. eol.checkheadshook only checks heads,
       intermediate invalid revisions will be pushed. To forbid them
       completely, use the eol.checkallhook hook. These hooks are best
       used as pretxnchangegroup hooks.

       See hg help patterns for more information about the glob patterns
       used.

   extdiff
       command to allow external programs to compare revisions

       The extdiff Mercurial extension allows you to use external
       programs to compare revisions, or revision with working
       directory. The external diff programs are called with a
       configurable set of options and two non-option arguments: paths
       to directories containing snapshots of files to compare.

       The extdiff extension also allows you to configure new diff
       commands, so you do not need to type hg extdiff -p kdiff3 always.

       [extdiff]
       # add new command that runs GNU diff(1) in 'context diff' mode
       cdiff = gdiff -Nprc5
       ## or the old way:
       #cmd.cdiff = gdiff
       #opts.cdiff = -Nprc5

       # add new command called vdiff, runs kdiff3
       vdiff = kdiff3

       # add new command called meld, runs meld (no need to name twice)
       meld =

       # add new command called vimdiff, runs gvimdiff with DirDiff plugin
       # (see http://www.vim.org/scripts/script.php?script_id=102) Non
       # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
       # your .vimrc
       vimdiff = gvim -f "+next" \
                 "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"

       Tool arguments can include variables that are expanded at
       runtime:

       $parent1, $plabel1 - filename, descriptive label of first parent
       $child,   $clabel  - filename, descriptive label of child revision
       $parent2, $plabel2 - filename, descriptive label of second parent
       $root              - repository root
       $parent is an alias for $parent1.

       The extdiff extension will look in your [diff-tools] and
       [merge-tools] sections for diff tool arguments, when none are
       specified in [extdiff].

       [extdiff]
       kdiff3 =

       [diff-tools]
       kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child

       You can use -I/-X and list of file or directory names like normal
       hg diff command. The extdiff extension makes snapshots of only
       needed files, so running the external diff program will actually
       be pretty fast (at least faster than having to compare the entire
       tree).

   Commands
   extdiff
       hg extdiff [OPT]... [FILE]...

       Show differences between revisions for the specified files, using
       an external program. The default program used is diff, with
       default options "-Npru".

       To select a different program, use the -p/--program option. The
       program will be passed the names of two directories to compare.
       To pass additional options to the program, use -o/--option. These
       will be passed before the names of the directories to compare.

       When two revision arguments are given, then changes are shown
       between those revisions. If only one revision is specified then
       that revision is compared to the working directory, and, when no
       revisions are specified, the working directory files are compared
       to its parent.

       Options:

       -p, --program
              comparison program to run

       -o, --option
              pass option to comparison program

       -r, --rev
              revision

       -c, --change
              change made by revision

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   factotum
       http authentication with factotum

       This extension allows the factotum(4) facility on Plan 9 from
       Bell Labs platforms to provide authentication information for
       HTTP access. Configuration entries specified in the auth section
       as well as authentication information provided in the repository
       URL are fully supported. If no prefix is specified, a value of
       "*" will be assumed.

       By default, keys are specified as:

       proto=pass service=hg prefix=<prefix> user=<username> !password=<password>

       If the factotum extension is unable to read the required key, one
       will be requested interactively.

       A configuration section is available to customize runtime
       behavior. By default, these entries are:

       [factotum]
       executable = /bin/auth/factotum
       mountpoint = /mnt/factotum
       service = hg

       The executable entry defines the full path to the factotum
       binary. The mountpoint entry defines the path to the factotum
       file service. Lastly, the service entry controls the service name
       used when reading keys.

   fetch
       pull, update and merge in one command (DEPRECATED)

   Commands
   fetch
       hg fetch [SOURCE]

       This finds all changes from the repository at the specified path
       or URL and adds them to the local repository.

       If the pulled changes add a new branch head, the head is
       automatically merged, and the result of the merge is committed.
       Otherwise, the working directory is updated to include the new
       changes.

       When a merge is needed, the working directory is first updated to
       the newly pulled changes. Local changes are then merged into the
       pulled changes. To switch the merge order, use --switch-parent.

       See hg help dates for a list of formats valid for -d/--date.

       Returns 0 on success.

       verify all the signatures there may be for a particular revision

   sign
       hg sign [OPTION]... [REV]...

       If no revision is given, the parent of the working directory is
       used, or tip if no revision is checked out.

       See hg help dates for a list of formats valid for -d/--date.

       Options:

       -l, --local
              make the signature local

              record the specified user as committer

   sigs
       hg sigs

       list signed changesets

   graphlog
       command to view revision graphs from a shell

       This extension adds a --graph option to the incoming, outgoing
       and log commands. When this options is given, an ASCII
       representation of the revision graph is also shown.

   Commands
   glog
       hg glog [OPTION]... [FILE]

       Print a revision history alongside a revision graph drawn with

   hgcia
       hooks for integrating with the CIA.vc notification service

       This is meant to be run as a changegroup or incoming hook. To
       configure it, set the following options in your hgrc:

       [cia]
       # your registered CIA user name
       user = foo
       # the name of the project in CIA
       project = foo
       # the module (subproject) (optional)
       #module = foo
       # Append a diffstat to the log message (optional)
       #diffstat = False
       # Template to use for log messages (optional)
       #template = {desc}\n{baseurl}{webroot}/rev/{node}-- {diffstat}
       # Style to use (optional)
       #style = foo
       # The URL of the CIA notification service (optional)
       # You can use mailto: URLs to send by email, e.g.
       # mailto:cia@cia.vc
       # Make sure to set email.from if you do this.
       #url = http://cia.vc/
       # print message instead of sending it (optional)
       #test = False
       # number of slashes to strip for url paths
       #strip = 0

       [hooks]
       # one of these:
       changegroup.cia = python:hgcia.hook
       #incoming.cia = python:hgcia.hook

       [web]
       # If you want hyperlinks (optional)
       baseurl = http://server/path/to/repo

   hgk
       browse the repository in a graphical way

       The hgk extension allows browsing the history of a repository in
       a graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk
       is not distributed with Mercurial.)

       hgk consists of two parts: a Tcl script that does the displaying
       and querying of information, and an extension to Mercurial named
       hgk.py, which provides hooks for hgk to get information. hgk can
       be found in the contrib directory, and the extension is shipped
       in the hgext repository, and needs to be enabled.

       The hg view command will launch the hgk Tcl script. For this
       command to work, hgk must be in your search path. Alternately,
       you can specify the path to hgk in your configuration file:

       [hgk]
       path=/location/of/hgk

       hgk can make use of the extdiff extension to visualize revisions.
       Assuming you had already configured extdiff vdiff command, just
       add:

       [hgk]
       vdiff=vdiff

       Revisions context menu will now display additional entries to
       fire vdiff on hovered and selected revisions.

   Commands
   view
       hg view [-l LIMIT] [REVRANGE]

       start interactive history viewer

       Options:

       -l, --limit
              limit number of changes displayed

   highlight
       syntax highlighting for hgweb (requires Pygments)

       It depends on the Pygments syntax highlighting library:
       http://pygments.org/

       There is a single configuration option:

       [web]
       pygments_style = <style>

       The default is 'colorful'.

   histedit
       interactive history editing

       With this extension installed, Mercurial gains one new command:
       histedit. Usage is as follows, assuming the following history:

       @  3[tip]   7c2fd3b9020c   2009-04-27 18:04 -0500   durin42
       |    Add delta
       |
       o  2   030b686bedc4   2009-04-27 18:04 -0500   durin42
       |    Add gamma
       |
       o  1   c561b4e977df   2009-04-27 18:04 -0500   durin42
       |    Add beta
       |
       o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
            Add alpha

       If you were to run hg histedit c561b4e977df, you would see the
       following file open in your editor:

       pick c561b4e977df Add beta
       pick 030b686bedc4 Add gamma
       pick 7c2fd3b9020c Add delta

       # Edit history between c561b4e977df and 7c2fd3b9020c
       #
       # Commands:
       #  p, pick = use commit
       #  e, edit = use commit, but stop for amending
       #  f, fold = use commit, but fold into previous commit (combines N and N-1)
       #  d, drop = remove commit from history
       #  m, mess = edit message without changing commit content
       #

       In this file, lines beginning with # are ignored. You must
       specify a rule for each revision in your history. For example, if
       you had meant to add gamma before beta, and then wanted to add
       delta in the same revision as beta, you would reorganize the file
       to look like this:

       pick 030b686bedc4 Add gamma
       pick c561b4e977df Add beta
       fold 7c2fd3b9020c Add delta

       # Edit history between c561b4e977df and 7c2fd3b9020c
       #
       # Commands:
       #  p, pick = use commit
       #  e, edit = use commit, but stop for amending
       #  f, fold = use commit, but fold into previous commit (combines N and N-1)
       #  d, drop = remove commit from history
       #  m, mess = edit message without changing commit content
       #

       At which point you close the editor and histedit starts working.
       When you specify a fold operation, histedit will open an editor
       when it folds those revisions together, offering you a chance to
       clean up the commit message:

       Add beta
       ***
       Add delta

       Edit the commit message to your liking, then close the editor.
       For this example, let's assume that the commit message was
       changed to Add beta and delta. After histedit has run and had a
       chance to remove any old or temporary revisions it needed, the
       history looks like this:

       @  2[tip]   989b4d060121   2009-04-27 18:04 -0500   durin42
       |    Add beta and delta.
       |
       o  1   081603921c3f   2009-04-27 18:04 -0500   durin42
       |    Add gamma
       |
       o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
            Add alpha

       Note that histedit does not remove any revisions (even its own
       temporary ones) until after it has completed all the editing
       operations, so it will probably perform several strip operations
       when it's done. For the above example, it had to run strip twice.
       Strip can be slow depending on a variety of factors, so you might
       need to be a little patient. You can choose to keep the original
       revisions by passing the --keep flag.

       The edit operation will drop you back to a command prompt,
       allowing you to edit files freely, or even use hg record to
       commit some changes as a separate commit. When you're done, any
       remaining uncommitted changes will be committed as well. When
       done, run hg histedit --continue to finish this step. You'll be
       prompted for a new commit message, but the default commit message
       will be the original message for the edit ed revision.

       The message operation will give you a chance to revise a commit
       message without changing the contents. It's a shortcut for doing
       edit immediately followed by hg histedit --continue`.

       If histedit encounters a conflict when moving a revision (while
       handling pick or fold), it'll stop in a similar manner to edit
       with the difference that it won't prompt you for a commit message
       when done. If you decide at this point that you don't like how
       much work it will be to rearrange history, or that you made a
       mistake, you can use hg histedit --abort to abandon the new
       changes you have made and return to the state before you
       attempted to edit your history.

       If we clone the histedit-ed example repository above and add four
       more changes, such that we have the following history:

       If you run hg histedit --outgoing on the clone then it is the
       same as running hg histedit 836302820282. If you need plan to
       push to a repository that Mercurial does not detect to be related
       to the source repo, you can add a --force option.

   keyword
       expand keywords in tracked files

       This extension expands RCS/CVS-like or self-customized $Keywords$
       in tracked text files selected by your configuration.

       Keywords are only expanded in local repositories and not stored
       in the change history. The mechanism can be regarded as a
       convenience for the current user or for archive distribution.

       Keywords expand to the changeset data pertaining to the latest
       change relative to the working directory parent of each file.

       Configuration is done in the [keyword], [keywordset] and
       [keywordmaps] sections of hgrc files.

       Example:

       [keyword]
       # expand keywords in every python file except those matching "x*"
       **.py =
       x*    = ignore

       [keywordset]
       # prefer svn- over cvs-like default keywordmaps
       svn = True

       Note   The more specific you are in your filename patterns the
              less you lose speed in huge repositories.

       For [keywordmaps] template mapping and expansion demonstration
       and control run hg kwdemo. See hg help templates for a list of
       available templates and filters.

       Three additional date template filters are provided:

       utcdate

              "2006/09/18 15:13:13"

       svnutcdate

              "2006-09-18 15:13:13Z"

       svnisodate

              "2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"

       The default template mappings (view with hg kwdemo -d) can be
       replaced with customized keywords and templates. Again, run hg
       kwdemo to control the results of your configuration changes.

       Before changing/disabling active keywords, you must run hg
       kwshrink to avoid storing expanded keywords in the change
       history.

       To force expansion after enabling it, or a configuration change,
       run hg kwexpand.

       Expansions spanning more than one line and incremental
       expansions, like CVS' $Log$, are not supported. A keyword
       template map "Log = {desc}" expands to the first line of the
       changeset description.

   Commands
   kwdemo
       hg kwdemo [-d] [-f RCFILE] [TEMPLATEMAP]...

       Show current, custom, or default keyword template maps and their
       expansions.

       Extend the current configuration by specifying maps as arguments
       and using -f/--rcfile to source an external hgrc file.

       Use -d/--default to disable current configuration.

       See hg help templates for information on templates and filters.

       Options:

       -d, --default
              show default keyword template maps

       -f, --rcfile
              read maps from rcfile

   kwexpand
       hg kwexpand [OPTION]... [FILE]...

       Run after (re)enabling keyword expansion.

       kwexpand refuses to run if given files contain local changes.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   kwfiles
       hg kwfiles [OPTION]... [FILE]...

       List which files in the working directory are matched by the
       [keyword] configuration patterns.

       Useful to prevent inadvertent keyword expansion and to speed up
       execution by including only files that are actual candidates for
       expansion.

       See hg help keyword on how to construct patterns both for
       inclusion and exclusion of files.

       With -A/--all and -v/--verbose the codes used to show the status
       of files are:

       K = keyword expansion candidate
       k = keyword expansion candidate (not tracked)
       I = ignored
       i = ignored (not tracked)

       Options:

       -A, --all
              show keyword status flags of all files

       -i, --ignore
              show files excluded from expansion

       -u, --unknown
              only show unknown (not tracked) files

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   kwshrink
       hg kwshrink [OPTION]... [FILE]...

       Must be run before changing/disabling active keywords.

       kwshrink refuses to run if given files contain local changes.

       Options:

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   largefiles
       track large binary files

       Large binary files tend to be not very compressible, not very
       diffable, and not at all mergeable. Such files are not handled
       efficiently by Mercurial's storage format (revlog), which is
       based on compressed binary deltas; storing large binary files as
       regular Mercurial files wastes bandwidth and disk space and
       increases Mercurial's memory usage. The largefiles extension
       addresses these problems by adding a centralized client-server
       layer on top of Mercurial: largefiles live in a central store out
       on the network somewhere, and you only fetch the revisions that
       you need when you need them.

       largefiles works by maintaining a "standin file" in .hglf/ for
       each largefile. The standins are small (41 bytes: an SHA-1 hash
       plus newline) and are tracked by Mercurial. Largefile revisions
       are identified by the SHA-1 hash of their contents, which is
       written to the standin. largefiles uses that revision ID to
       get/put largefile revisions from/to the central store. This saves
       both disk space and bandwidth, since you don't need to retrieve
       all historical revisions of large files when you clone or pull.

       To start a new repository or add new large binary files, just add
       --large to your hg add command. For example:

       $ dd if=/dev/urandom of=randomdata count=2000
       $ hg add --large randomdata
       $ hg commit -m 'add randomdata as a largefile'

       When you push a changeset that adds/modifies largefiles to a
       remote repository, its largefile revisions will be uploaded along
       with it.  Note that the remote Mercurial must also have the
       largefiles extension enabled for this to work.

       When you pull a changeset that affects largefiles from a remote
       repository, the largefiles for the changeset will by default not
       be pulled down. However, when you update to such a revision, any
       largefiles needed by that revision are downloaded and cached (if
       they have never been downloaded before). One way to pull
       largefiles when pulling is thus to use --update, which will
       update your working copy to the latest pulled revision (and
       thereby downloading any new largefiles).

       If you want to pull largefiles you don't need for update yet,
       then you can use pull with the --lfrev option or the hg lfpull
       command.

       If you know you are pulling from a non-default location and want
       to download all the largefiles that correspond to the new
       changesets at the same time, then you can pull with --lfrev
       "pulled()".

       If you just want to ensure that you will have the largefiles
       needed to merge or rebase with new heads that you are pulling,
       then you can pull with --lfrev "head(pulled())" flag to
       pre-emptively download any largefiles that are new in the heads
       you are pulling.

       Keep in mind that network access may now be required to update to
       changesets that you have not previously updated to. The nature of
       the largefiles extension means that updating is no longer
       guaranteed to be a local-only operation.

       If you already have large files tracked by Mercurial without the
       largefiles extension, you will need to convert your repository in
       order to benefit from largefiles. This is done with the hg
       lfconvert command:

       $ hg lfconvert --size 10 oldrepo newrepo

       In repositories that already have largefiles in them, any new
       file over 10MB will automatically be added as a largefile. To
       change this threshold, set largefiles.minsize in your Mercurial
       config file to the minimum size in megabytes to track as a
       largefile, or use the --lfsize option to the add command (also in
       megabytes):

       [largefiles]
       minsize = 2

       $ hg add --lfsize 2

       The largefiles.patterns config option allows you to specify a
       list of filename patterns (see hg help patterns) that should
       always be tracked as largefiles:

       [largefiles]
       patterns =
         *.jpg
         re:.*\.(png|bmp)$
         library.zip
         content/audio/*

       Files that match one of these patterns will be added as
       largefiles regardless of their size.

       The largefiles.minsize and largefiles.patterns config options
       will be ignored for any repositories not already containing a
       largefile. To add the first largefile to a repository, you must
       explicitly do so with the --large flag passed to the hg add
       command.

   Commands
   lfconvert
       hg lfconvert SOURCE DEST [FILE ...]

       Convert repository SOURCE to a new repository DEST, identical to
       SOURCE except that certain files will be converted as largefiles:
       specifically, any file that matches any PATTERN or whose size is
       above the minimum size threshold is converted as a largefile. The
       size used to determine whether or not to track a file as a
       largefile is the size of the first version of the file. The
       minimum size can be specified either with --size or in
       configuration as largefiles.size.

       After running this command you will need to make sure that
       largefiles is enabled anywhere you intend to push the new
       repository.

       Use --to-normal to convert largefiles back to normal files; after
       this, the DEST repository can be used without largefiles at all.

       Options:

       -s, --size
              minimum size (MB) for files to be converted as largefiles

       --to-normal
              convert from a largefiles repo to a normal repo

   lfpull
       hg lfpull -r REV... [-e CMD] [--remotecmd CMD] [SOURCE]

       Pull largefiles that are referenced from local changesets but
       missing locally, pulling from a remote repository to the local
       cache.

       If SOURCE is omitted, the 'default' path will be used.  See hg
       help urls for more information.

       Some examples:

       • pull largefiles for all branch heads:

         hg lfpull -r "head() and not closed()"

       • pull largefiles on the default branch:

         hg lfpull -r "branch(default)"

       Options:

       -r, --rev
              pull largefiles for these revisions

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

   mq
       manage a stack of patches

       This extension lets you work with a stack of patches in a
       Mercurial repository. It manages two stacks of patches - all
       known patches, and applied patches (subset of known patches).

       Known patches are represented as patch files in the .hg/patches
       directory. Applied patches are both patch files and changesets.

       Common tasks (use hg help command for more details):

       create new patch                          qnew
       import existing patch                     qimport

       print patch series                        qseries
       print applied patches                     qapplied

       add known patch to applied stack          qpush
       remove patch from applied stack           qpop
       refresh contents of top applied patch     qrefresh

       By default, mq will automatically use git patches when required
       to avoid losing file mode changes, copy records, binary files or
       empty files creations or deletions. This behaviour can be
       configured with:

       [mq]
       git = auto/keep/yes/no

       If set to 'keep', mq will obey the [diff] section configuration
       while preserving existing git patches upon qrefresh. If set to
       'yes' or 'no', mq will override the [diff] section and always
       generate git or regular patches, possibly losing data in the
       second case.

       It may be desirable for mq changesets to be kept in the secret
       phase (see hg help phases), which can be enabled with the
       following setting:

       [mq]
       secret = True

       You will by default be managing a patch queue named "patches".
       You can create other, independent patch queues with the hg qqueue
       command.

       If the working directory contains uncommitted files, qpush, qpop
       and qgoto abort immediately. If -f/--force is used, the changes
       are discarded. Setting:

       [mq]
       keepchanges = True

       make them behave as if --keep-changes were passed, and
       non-conflicting local changes will be tolerated and preserved. If
       incompatible options such as -f/--force or --exact are passed,
       this setting is ignored.

   Commands
   qapplied
       hg qapplied [-1] [-s] [PATCH]

       Returns 0 on success.

       Options:

       -1, --last
              show only the preceding applied patch

       -s, --summary
              print first line of patch header

   qclone
       hg qclone [OPTION]... SOURCE [DEST]

       If source is local, destination will have no patches applied. If
       source is remote, this command can not check if patches are
       applied in source, so cannot guarantee that patches are not
       applied in destination. If you clone remote repository, be sure
       before that it has no patches applied.

       Source patch repository is looked for in <src>/.hg/patches by
       default. Use -p <url> to change.

       The patch directory must be a nested Mercurial repository, as
       would be created by hg init --mq.

       Return 0 on success.

       Options:

       --pull use pull protocol to copy metadata

       -U, --noupdate
              do not update the new working directories

       --uncompressed
              use uncompressed transfer (fast over LAN)

       -p, --patches
              location of source patch repository

       -e, --ssh
              specify ssh command to use

       --remotecmd
              specify hg command to run on the remote side

       --insecure
              do not verify server certificate (ignoring web.cacerts
              config)

   qcommit
       hg qcommit [OPTION]... [FILE]...

       This command is deprecated; use hg commit --mq instead.

       Options:

       -A, --addremove
              mark new/missing files as added/removed before committing

       --close-branch
              mark a branch as closed, hiding it from the branch list

       --amend
              amend the parent of the working dir

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

       -d, --date
              record the specified date as commit date

       -u, --user
              record the specified user as committer

       -S, --subrepos
              recurse into subrepositories

              aliases: qci

   qdelete
       hg qdelete [-k] [PATCH]...

       The patches must not be applied, and at least one patch is
       required. Exact patch identifiers must be given. With -k/--keep,
       the patch files are preserved in the patch directory.

       To stop managing a patch and move it into permanent history, use
       the hg qfinish command.

       Options:

       -k, --keep
              keep patch file

       -r, --rev
              stop managing a revision (DEPRECATED)

              aliases: qremove qrm

   qdiff
       hg qdiff [OPTION]... [FILE]...

       Shows a diff which includes the current patch as well as any
       changes which have been made in the working directory since the
       last refresh (thus showing what the current patch would become
       after a qrefresh).

       Use hg diff if you only want to see the changes made since the
       last qrefresh, or hg export qtip if you want to see changes made
       by the current patch without including changes made since the
       qrefresh.

       Returns 0 on success.

       Options:

       -a, --text
              treat all files as text

       -g, --git
              use git extended diff format

       --nodates
              omit dates from diff headers

       -p, --show-function
              show which function each change is in

       --reverse
              produce a diff that undoes the changes

       -w, --ignore-all-space
              ignore white space when comparing lines

       -b, --ignore-space-change
              ignore changes in the amount of white space

       -B, --ignore-blank-lines
              ignore changes whose lines are all blank

       -U, --unified
              number of lines of context to show

       --stat output diffstat-style summary of changes

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

   qfinish
       hg qfinish [-a] [REV]...

       Finishes the specified revisions (corresponding to applied
       patches) by moving them out of mq control into regular repository
       history.

       Accepts a revision range or the -a/--applied option. If --applied
       is specified, all applied mq revisions are removed from mq
       control. Otherwise, the given revisions must be at the base of
       the stack of applied patches.

       This can be especially useful if your changes have been applied
       to an upstream repository, or if you are about to push your
       changes to upstream.

       Returns 0 on success.

       Options:

       -a, --applied
              finish all applied changesets

   qfold
       hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...

       Patches must not yet be applied. Each patch will be successively
       applied to the current patch in the order given. If all the
       patches apply successfully, the current patch will be refreshed
       with the new cumulative patch, and the folded patches will be
       deleted. With -k/--keep, the folded patch files will not be
       removed afterwards.

       The header for each folded patch will be concatenated with the
       current patch header, separated by a line of * * *.

       Returns 0 on success.

       Options:

       -e, --edit
              edit patch header

       -k, --keep
              keep folded patch files

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   qgoto
       hg qgoto [OPTION]... PATCH

       Returns 0 on success.

       Options:

       --keep-changes
              tolerate non-conflicting local changes

       -f, --force
              overwrite any local changes

       --no-backup
              do not save backup copies of files

   qguard
       hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]

       Guards control whether a patch can be pushed. A patch with no
       guards is always pushed. A patch with a positive guard ("+foo")
       is pushed only if the hg qselect command has activated it. A
       patch with a negative guard ("-foo") is never pushed if the hg
       qselect command has activated it.

       With no arguments, print the currently active guards.  With
       arguments, set guards for the named patch.

       Note   Specifying negative guards now requires '--'.

       To set guards on another patch:

       hg qguard other.patch -- +2.6.17 -stable

       Returns 0 on success.

       Options:

       -l, --list
              list all patches and guards

       -n, --none
              drop all guards

   qheader
       hg qheader [PATCH]

       Returns 0 on success.

   qimport
       hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... [FILE]...

       The patch is inserted into the series after the last applied
       patch. If no patches have been applied, qimport prepends the
       patch to the series.

       The patch will have the same name as its source file unless you
       give it a new one with -n/--name.

       You can register an existing patch inside the patch directory
       with the -e/--existing flag.

       With -f/--force, an existing patch of the same name will be
       overwritten.

       An existing changeset may be placed under mq control with
       -r/--rev (e.g. qimport --rev tip -n patch will place tip under mq
       control).  With -g/--git, patches imported with --rev will use
       the git diff format. See the diffs help topic for information on
       why this is important for preserving rename/copy information and
       permission changes. Use hg qfinish to remove changesets from mq
       control.

       To import a patch from standard input, pass - as the patch file.
       When importing from standard input, a patch name must be
       specified using the --name flag.

       To import an existing patch while renaming it:

       hg qimport -e existing-patch -n new-name

       Returns 0 if import succeeded.

       Options:

       -e, --existing
              import file in patch directory

       -n, --name
              name of patch file

       -f, --force
              overwrite existing files

       -r, --rev
              place existing revisions under mq control

       -g, --git
              use git extended diff format

       -P, --push
              qpush after importing

   qinit
       hg qinit [-c]

       The queue repository is unversioned by default. If
       -c/--create-repo is specified, qinit will create a separate
       nested repository for patches (qinit -c may also be run later to
       convert an unversioned patch repository into a versioned one).
       You can use qcommit to commit changes to this queue repository.

       This command is deprecated. Without -c, it's implied by other
       relevant commands. With -c, use hg init --mq instead.

       Options:

       -c, --create-repo
              create queue repository

   qnew
       hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...

       qnew creates a new patch on top of the currently-applied patch
       (if any). The patch will be initialized with any outstanding
       changes in the working directory. You may also use -I/--include,
       -X/--exclude, and/or a list of files after the patch name to add
       only changes to matching files to the new patch, leaving the rest
       as uncommitted modifications.

       -u/--user and -d/--date can be used to set the (given) user and
       date, respectively. -U/--currentuser and -D/--currentdate set
       user to current user and date to current date.

       -e/--edit, -m/--message or -l/--logfile set the patch header as
       well as the commit message. If none is specified, the header is
       empty and the commit message is '[mq]: PATCH'.

       Use the -g/--git option to keep the patch in the git extended
       diff format. Read the diffs help topic for more information on
       why this is important for preserving permission changes and
       copy/rename information.

       Returns 0 on successful creation of a new patch.

       Options:

       -e, --edit
              edit commit message

       -f, --force
              import uncommitted changes (DEPRECATED)

       -g, --git
              use git extended diff format

       -U, --currentuser
              add "From: <current user>" to patch

       -u, --user
              add "From: <USER>" to patch

       -D, --currentdate
              add "Date: <current date>" to patch

       -d, --date
              add "Date: <DATE>" to patch

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   qnext
       hg qnext [-s]

       Returns 0 on success.

       Options:

       -s, --summary
              print first line of patch header

   qpop
       hg qpop [-a] [-f] [PATCH | INDEX]

       Without argument, pops off the top of the patch stack. If given a
       patch name, keeps popping off patches until the named patch is at
       the top of the stack.

       By default, abort if the working directory contains uncommitted
       changes. With --keep-changes, abort only if the uncommitted files
       overlap with patched files. With -f/--force, backup and discard
       changes made to such files.

       Return 0 on success.

       Options:

       -a, --all
              pop all patches

       -n, --name
              queue name to pop (DEPRECATED)

       --keep-changes
              tolerate non-conflicting local changes

       -f, --force
              forget any local changes to patched files

       --no-backup
              do not save backup copies of files

   qprev
       hg qprev [-s]

       Returns 0 on success.

       Options:

       -s, --summary
              print first line of patch header

   qpush
       hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]

       By default, abort if the working directory contains uncommitted
       changes. With --keep-changes, abort only if the uncommitted files
       overlap with patched files. With -f/--force, backup and patch
       over uncommitted changes.

       Return 0 on success.

       Options:

       --keep-changes
              tolerate non-conflicting local changes

       -f, --force
              apply on top of local changes

       -e, --exact
              apply the target patch to its recorded parent

       -l, --list
              list patch name in commit text

       -a, --all
              apply all patches

       -m, --merge
              merge from another queue (DEPRECATED)

       -n, --name
              merge queue name (DEPRECATED)

       --move reorder patch series and apply only the patch

       --no-backup
              do not save backup copies of files

   qqueue
       hg qqueue [OPTION] [QUEUE]

       Supports switching between different patch queues, as well as
       creating new patch queues and deleting existing ones.

       Omitting a queue name or specifying -l/--list will show you the
       registered queues - by default the "normal" patches queue is
       registered. The currently active queue will be marked with
       "(active)". Specifying --active will print only the name of the
       active queue.

       To create a new queue, use -c/--create. The queue is
       automatically made active, except in the case where there are
       applied patches from the currently active queue in the
       repository. Then the queue will only be created and switching
       will fail.

       To delete an existing queue, use --delete. You cannot delete the
       currently active queue.

       Returns 0 on success.

       Options:

       -l, --list
              list all available queues

       --active
              print name of active queue

       -c, --create
              create new queue

       --rename
              rename active queue

       --delete
              delete reference to queue

       --purge
              delete queue, and remove patch dir

   qrefresh
       hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...

       If any file patterns are provided, the refreshed patch will
       contain only the modifications that match those patterns; the
       remaining modifications will remain in the working directory.

       If -s/--short is specified, files currently included in the patch
       will be refreshed just like matched files and remain in the
       patch.

       If -e/--edit is specified, Mercurial will start your configured
       editor for you to enter a message. In case qrefresh fails, you
       will find a backup of your message in .hg/last-message.txt.

       hg add/remove/copy/rename work as usual, though you might want to
       use git-style patches (-g/--git or [diff] git=1) to track copies
       and renames. See the diffs help topic for more information on the
       git diff format.

       Returns 0 on success.

       Options:

       -e, --edit
              edit commit message

       -g, --git
              use git extended diff format

       -s, --short
              refresh only files already in the patch and specified
              files

       -U, --currentuser
              add/update author field in patch with current user

       -u, --user
              add/update author field in patch with given user

       -D, --currentdate
              add/update date field in patch with current date

       -d, --date
              add/update date field in patch with given date

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   qrename
       hg qrename PATCH1 [PATCH2]

       With one argument, renames the current patch to PATCH1.  With two
       arguments, renames PATCH1 to PATCH2.

       Returns 0 on success.

          aliases: qmv

   qrestore
       hg qrestore [-d] [-u] REV

       This command is deprecated, use hg rebase instead.

       Options:

       -d, --delete
              delete save entry

       -u, --update
              update queue working directory

   qsave
       hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]

       This command is deprecated, use hg rebase instead.

       Options:

       -c, --copy
              copy patch directory

       -n, --name
              copy directory name

       -e, --empty
              clear queue status file

       -f, --force
              force copy

       -m, --message
              use text as commit message

       -l, --logfile
              read commit message from file

   qselect
       hg qselect [OPTION]... [GUARD]...

       Use the hg qguard command to set or print guards on patch, then
       use qselect to tell mq which guards to use. A patch will be
       pushed if it has no guards or any positive guards match the
       currently selected guard, but will not be pushed if any negative
       guards match the current guard. For example:

       qguard foo.patch -- -stable    (negative guard)
       qguard bar.patch    +stable    (positive guard)
       qselect stable

       This activates the "stable" guard. mq will skip foo.patch
       (because it has a negative match) but push bar.patch (because it
       has a positive match).

       With no arguments, prints the currently active guards.  With one
       argument, sets the active guard.

       Use -n/--none to deactivate guards (no other arguments needed).
       When no guards are active, patches with positive guards are
       skipped and patches with negative guards are pushed.

       qselect can change the guards on applied patches. It does not pop
       guarded patches by default. Use --pop to pop back to the last
       applied patch that is not guarded. Use --reapply (which implies
       --pop) to push back to the current patch afterwards, but skip
       guarded patches.

       Use -s/--series to print a list of all guards in the series file
       (no other arguments needed). Use -v for more information.

       Returns 0 on success.

       Options:

       -n, --none
              disable all guards

       -s, --series
              list all guards in series file

       --pop  pop to before first guarded applied patch

       --reapply
              pop, then reapply patches

   qseries
       hg qseries [-ms]

       Returns 0 on success.

       Options:

       -m, --missing
              print patches not in series

       -s, --summary
              print first line of patch header

   qtop
       hg qtop [-s]

       Returns 0 on success.

       Options:

       -s, --summary
              print first line of patch header

   qunapplied
       hg qunapplied [-1] [-s] [PATCH]

       Returns 0 on success.

       Options:

       -1, --first
              show only the first patch

       -s, --summary
              print first line of patch header

   strip
       hg strip [-k] [-f] [-n] [-B bookmark] [-r] REV...

       The strip command removes the specified changesets and all their
       descendants. If the working directory has uncommitted changes,
       the operation is aborted unless the --force flag is supplied, in
       which case changes will be discarded.

       If a parent of the working directory is stripped, then the
       working directory will automatically be updated to the most
       recent available ancestor of the stripped parent after the
       operation completes.

       Any stripped changesets are stored in .hg/strip-backup as a
       bundle (see hg help bundle and hg help unbundle). They can be
       restored by running hg unbundle .hg/strip-backup/BUNDLE, where
       BUNDLE is the bundle file created by the strip. Note that the
       local revision numbers will in general be different after the
       restore.

       Use the --no-backup option to discard the backup bundle once the
       operation completes.

       Strip is not a history-rewriting operation and can be used on
       changesets in the public phase. But if the stripped changesets
       have been pushed to a remote repository you will likely pull them
       again.

       Return 0 on success.

       Options:

       -r, --rev
              strip specified revision (optional, can specify revisions
              without this option)

       -f, --force
              force removal of changesets, discard uncommitted changes
              (no backup)

       -b, --backup
              bundle only changesets with local revision number greater
              than REV which are not descendants of REV (DEPRECATED)

       --no-backup
              no backups

       --nobackup
              no backups (DEPRECATED)

       -n     ignored  (DEPRECATED)

       -k, --keep
              do not modify working copy during strip

       -B, --bookmark
              remove revs only reachable from given bookmark

   notify
       hooks for sending email push notifications

       This extension implements hooks to send email notifications when
       changesets are sent from or received by the local repository.

       First, enable the extension as explained in hg help extensions,
       and register the hook you want to run. incoming and changegroup
       hooks are run when changesets are received, while outgoing hooks
       are for changesets sent to another repository:

       [hooks]
       # one email for each incoming changeset
       incoming.notify = python:hgext.notify.hook
       # one email for all incoming changesets
       changegroup.notify = python:hgext.notify.hook

       # one email for all outgoing changesets
       outgoing.notify = python:hgext.notify.hook

       This registers the hooks. To enable notification, subscribers
       must be assigned to repositories. The [usersubs] section maps
       multiple repositories to a given recipient. The [reposubs]
       section maps multiple recipients to a single repository:

       [usersubs]
       # key is subscriber email, value is a comma-separated list of repo patterns
       user@host = pattern

       [reposubs]
       # key is repo pattern, value is a comma-separated list of subscriber emails
       pattern = user@host

       A pattern is a glob matching the absolute path to a repository,
       optionally combined with a revset expression. A revset
       expression, if present, is separated from the glob by a hash.
       Example:

       [reposubs]
       */widgets#branch(release) = qa-team@example.com

       This sends to qa-team@example.com whenever a changeset on the
       release branch triggers a notification in any repository ending
       in widgets.

       In order to place them under direct user management, [usersubs]
       and [reposubs] sections may be placed in a separate hgrc file and
       incorporated by reference:

       [notify]
       config = /path/to/subscriptionsfile

       Notifications will not be sent until the notify.test value is set
       to False; see below.

       Notifications content can be tweaked with the following
       configuration entries:

       notify.test
              If True, print messages to stdout instead of sending them.
              Default: True.

       notify.sources
              Space-separated list of change sources. Notifications are
              activated only when a changeset's source is in this list.
              Sources may be:

              serve

                     changesets received via http or ssh

              pull

                     changesets received via hg pull

              unbundle

                     changesets received via hg unbundle

              push

                     changesets sent or received via hg push

              bundle

                     changesets sent via hg unbundle

              Default: serve.

       notify.strip
              Number of leading slashes to strip from url paths. By
              default, notifications reference repositories with their
              absolute path. notify.strip lets you turn them into
              relative paths. For example, notify.strip=3 will change
              /long/path/repository into repository. Default: 0.

       notify.domain
              Default email domain for sender or recipients with no
              explicit domain.

       notify.style
              Style file to use when formatting emails.

       notify.template
              Template to use when formatting emails.

       notify.incoming
              Template to use when run as an incoming hook, overriding
              notify.template.

       notify.outgoing
              Template to use when run as an outgoing hook, overriding
              notify.template.

       notify.changegroup
              Template to use when running as a changegroup hook,
              overriding notify.template.

       notify.maxdiff
              Maximum number of diff lines to include in notification
              email. Set to 0 to disable the diff, or -1 to include all
              of it. Default: 300.

       notify.maxsubject
              Maximum number of characters in email's subject line.
              Default: 67.

       notify.diffstat
              Set to True to include a diffstat before diff content.
              Default: True.

       notify.merge
              If True, send notifications for merge changesets. Default:
              True.

       notify.mbox
              If set, append mails to this mbox file instead of sending.
              Default: None.

       notify.fromauthor
              If set, use the committer of the first changeset in a
              changegroup for the "From" field of the notification mail.
              If not set, take the user from the pushing repo.  Default:
              False.

       If set, the following entries will also be used to customize the
       notifications:

       email.from
              Email From address to use if none can be found in the
              generated email content.

       web.baseurl
              Root repository URL to combine with repository paths when
              making references. See also notify.strip.

   pager
       browse command output with an external pager

       To set the pager that should be used, set the application
       variable:

       [pager]
       pager = less -FRX

       If no pager is set, the pager extensions uses the environment
       variable $PAGER. If neither pager.pager, nor $PAGER is set, no
       pager is used.

       You can disable the pager for certain commands by adding them to
       the pager.ignore list:

       [pager]
       ignore = version, help, update

       You can also enable the pager only for certain commands using
       pager.attend. Below is the default list of commands to be paged:

       [pager]
       attend = annotate, cat, diff, export, glog, log, qdiff

       Setting pager.attend to an empty value will cause all commands to
       be paged.

       If pager.attend is present, pager.ignore will be ignored.

       To ignore global commands like hg version or hg help, you have to
       specify them in your user configuration file.

       The --pager=... option can also be used to control when the pager
       is used. Use a boolean value like yes, no, on, off, or use auto
       for normal behavior.

   patchbomb
       command to send changesets as (a series of) patch emails

       The series is started off with a "[PATCH 0 of N]" introduction,
       which describes the series as a whole.

       Each patch email has a Subject line of "[PATCH M of N] ...",
       using the first line of the changeset description as the subject
       text. The message contains two or three body parts:

       • The changeset description.

       • [Optional] The result of running diffstat on the patch.

       • The patch itself, as generated by hg export.

       Each message refers to the first in the series using the
       In-Reply-To and References headers, so they will show up as a
       sequence in threaded mail and news readers, and in mail archives.

       To configure other defaults, add a section like this to your
       configuration file:

       [email]
       from = My Name <my@email>
       to = recipient1, recipient2, ...
       cc = cc1, cc2, ...
       bcc = bcc1, bcc2, ...
       reply-to = address1, address2, ...

       Use [patchbomb] as configuration section name if you need to
       override global [email] address settings.

       Then you can use the hg email command to mail a series of
       changesets as a patchbomb.

       You can also either configure the method option in the email
       section to be a sendmail compatible mailer or fill out the [smtp]
       section so that the patchbomb extension can automatically send
       patchbombs directly from the commandline. See the [email] and
       [smtp] sections in hgrc(5) for details.

   Commands
   email
       hg email [OPTION]... [DEST]...

       By default, diffs are sent in the format generated by hg export,
       one per message. The series starts with a "[PATCH 0 of N]"
       introduction, which describes the series as a whole.

       Each patch email has a Subject line of "[PATCH M of N] ...",
       using the first line of the changeset description as the subject
       text.  The message contains two or three parts. First, the
       changeset description.

       With the -d/--diffstat option, if the diffstat program is
       installed, the result of running diffstat on the patch is
       inserted.

       Finally, the patch itself, as generated by hg export.

       With the -d/--diffstat or --confirm options, you will be
       presented with a final summary of all messages and asked for
       confirmation before the messages are sent.

       By default the patch is included as text in the email body for
       easy reviewing. Using the -a/--attach option will instead create
       an attachment for the patch. With -i/--inline an inline
       attachment will be created. You can include a patch both as text
       in the email body and as a regular or an inline attachment by
       combining the -a/--attach or -i/--inline with the --body option.

       With -o/--outgoing, emails will be generated for patches not
       found in the destination repository (or only those which are
       ancestors of the specified revisions if any are provided)

       With -b/--bundle, changesets are selected as for --outgoing, but
       a single email containing a binary Mercurial bundle as an
       attachment will be sent.

       With -m/--mbox, instead of previewing each patchbomb message in a
       pager or sending the messages directly, it will create a UNIX
       mailbox file with the patch emails. This mailbox file can be
       previewed with any mail user agent which supports UNIX mbox
       files.

       With -n/--test, all steps will run, but mail will not be sent.
       You will be prompted for an email recipient address, a subject
       and an introductory message describing the patches of your
       patchbomb.  Then when all is done, patchbomb messages are
       displayed. If the PAGER environment variable is set, your pager
       will be fired up once for each patchbomb message, so you can
       verify everything is alright.

       In case email sending fails, you will find a backup of your
       series introductory message in .hg/last-email.txt.

       Examples:

       hg email -r 3000          # send patch 3000 only
       hg email -r 3000 -r 3001  # send patches 3000 and 3001
       hg email -r 3000:3005     # send patches 3000 through 3005
       hg email 3000             # send patch 3000 (deprecated)

       hg email -o               # send all patches not in default
       hg email -o DEST          # send all patches not in DEST
       hg email -o -r 3000       # send all ancestors of 3000 not in default
       hg email -o -r 3000 DEST  # send all ancestors of 3000 not in DEST

       hg email -b               # send bundle of all patches not in default
       hg email -b DEST          # send bundle of all patches not in DEST
       hg email -b -r 3000       # bundle of all ancestors of 3000 not in default
       hg email -b -r 3000 DEST  # bundle of all ancestors of 3000 not in DEST

       hg email -o -m mbox &&    # generate an mbox file...
         mutt -R -f mbox         # ... and view it with mutt
       hg email -o -m mbox &&    # generate an mbox file ...
         formail -s sendmail \   # ... and use formail to send from the mbox
           -bm -t < mbox         # ... using sendmail

       Before using this command, you will need to enable email in your
       hgrc. See the [email] section in hgrc(5) for details.

   progress
       show progress bars for some actions

       This extension uses the progress information logged by hg
       commands to draw progress bars that are as informative as
       possible. Some progress bars only offer indeterminate
       information, while others have a definite end point.

       The following settings are available:

       [progress]
       delay = 3 # number of seconds (float) before showing the progress bar
       changedelay = 1 # changedelay: minimum delay before showing a new topic.
                       # If set to less than 3 * refresh, that value will
                       # be used instead.
       refresh = 0.1 # time in seconds between refreshes of the progress bar
       format = topic bar number estimate # format of the progress bar
       width = <none> # if set, the maximum width of the progress information
                      # (that is, min(width, term width) will be used)
       clear-complete = True # clear the progress bar after it's done
       disable = False # if true, don't show a progress bar
       assume-tty = False # if true, ALWAYS show a progress bar, unless
                          # disable is given

       Valid entries for the format field are topic, bar, number, unit,
       estimate, speed, and item. item defaults to the last 20
       characters of the item, but this can be changed by adding either
       -<num> which would take the last num characters, or +<num> for
       the first num characters.

   purge
       command to delete untracked files from the working directory

   Commands
   purge
       hg purge [OPTION]... [DIR]...

       Delete files not known to Mercurial. This is useful to test local
       and uncommitted changes in an otherwise-clean source tree.

       This means that purge will delete:

       • Unknown files: files marked with "?" by hg status

       • Empty directories: in fact Mercurial ignores directories unless
         they contain files under source control management

       But it will leave untouched:

       • Modified and unmodified tracked files

       • Ignored files (unless --all is specified)

       • New files added to the repository (with hg add)

       If directories are given on the command line, only files in these
       directories are considered.

       Be careful with purge, as you could irreversibly delete some
       files you forgot to add to the repository. If you only want to
       print the list of files that this program would delete, use the
       --print option.

       Options:

       -a, --abort-on-err
              abort if an error occurs

       --all  purge ignored files too

       -p, --print
              print filenames instead of deleting them

       -0, --print0
              end filenames with NUL, for use with xargs (implies
              -p/--print)

       -I, --include
              include names matching the given patterns

       -X, --exclude
              exclude names matching the given patterns

              aliases: clean

   rebase
       command to move sets of revisions to a different ancestor

       This extension lets you rebase changesets in an existing
       Mercurial repository.

       For more information:
       http://mercurial.selenic.com/wiki/RebaseExtension

   Commands
   rebase
       hg rebase [-s REV | -b REV] [-d REV] [OPTION]

       Rebase uses repeated merging to graft changesets from one part of
       history (the source) onto another (the destination). This can be
       useful for linearizing local changes relative to a master
       development tree.

       You should not rebase changesets that have already been shared
       with others. Doing so will force everybody else to perform the
       same rebase or they will end up with duplicated changesets after
       pulling in your rebased changesets.

       In its default configuration, Mercurial will prevent you from
       rebasing published changes. See hg help phases for details.

       If you don't specify a destination changeset (-d/--dest), rebase
       uses the tipmost head of the current named branch as the
       destination. (The destination changeset is not modified by
       rebasing, but new changesets are added as its descendants.)

       You can specify which changesets to rebase in two ways: as a
       "source" changeset or as a "base" changeset. Both are shorthand
       for a topologically related set of changesets (the "source
       branch"). If you specify source (-s/--source), rebase will rebase
       that changeset and all of its descendants onto dest. If you
       specify base (-b/--base), rebase will select ancestors of base
       back to but not including the common ancestor with dest. Thus, -b
       is less precise but more convenient than -s: you can specify any
       changeset in the source branch, and rebase will select the whole
       branch. If you specify neither -s nor -b, rebase uses the parent
       of the working directory as the base.

       For advanced usage, a third way is available through the --rev
       option. It allows you to specify an arbitrary set of changesets
       to rebase. Descendants of revs you specify with this option are
       not automatically included in the rebase.

       By default, rebase recreates the changesets in the source branch
       as descendants of dest and then destroys the originals. Use
       --keep to preserve the original source changesets. Some
       changesets in the source branch (e.g. merges from the destination
       branch) may be dropped if they no longer contribute any change.

       One result of the rules for selecting the destination changeset
       and source branch is that, unlike merge, rebase will do nothing
       if you are at the latest (tipmost) head of a named branch with
       two heads. You need to explicitly specify source and/or
       destination (or update to the other head, if it's the head of the
       intended source branch).

       If a rebase is interrupted to manually resolve a merge, it can be
       continued with --continue/-c or aborted with --abort/-a.

       Returns 0 on success, 1 if nothing to rebase.

       Options:

       -s, --source
              rebase from the specified changeset

       -b, --base
              rebase from the base of the specified changeset (up to
              greatest common ancestor of base and dest)

       -r, --rev
              rebase these revisions

       -d, --dest
              rebase onto the specified changeset

       --collapse
              collapse the rebased changesets

       -m, --message
              use text as collapse commit message

       -e, --edit
              invoke editor on commit messages

       -l, --logfile
              read collapse commit message from file

       --keep keep original changesets

       --keepbranches
              keep original branch names

       -D, --detach
              (DEPRECATED)

       -t, --tool
              specify merge tool

       -c, --continue
              continue an interrupted rebase

       -a, --abort
              abort an interrupted rebase

       --style
              display using template map file

       --template
              display with template

   record
       commands to interactively select changes for commit/qrefresh

   Commands
   qrecord
       hg qrecord [OPTION]... PATCH [FILE]...

       See hg help qnew & hg help record for more information and usage.

   record
       hg record [OPTION]... [FILE]...

       If a list of files is omitted, all changes reported by hg status
       will be candidates for recording.

       See hg help dates for a list of formats valid for -d/--date.

       You will be prompted for whether to record changes to each
       modified file, and for files with multiple changes, for each
       change to use. For each query, the following responses are
       possible:

       y - record this change
       n - skip this change
       e - edit this change manually

       s - skip remaining changes to this file
       f - record remaining changes to this file

       d - done, skip remaining changes and files
       a - record all changes to all remaining files
       q - quit, recording no changes

       ? - display help

       This command is not available when committing a merge.

       Options:

       -A, --addremove
              mark new/missing files as added/removed before committing

       --close-branch
              mark a branch as closed, hiding it from the branch list

       -u, --user
              record the specified user as committer

       -S, --subrepos
              recurse into subrepositories

       -w, --ignore-all-space
              ignore white space when comparing lines

       -b, --ignore-space-change
              ignore changes in the amount of white space

       -B, --ignore-blank-lines
              ignore changes whose lines are all blank

   relink
       recreates hardlinks between repository clones

   Commands
   relink
       hg relink [ORIGIN]

       When repositories are cloned locally, their data files will be
       hardlinked so that they only use the space of a single
       repository.

       Unfortunately, subsequent pulls into either repository will break
       hardlinks for any files touched by the new changesets, even if
       both repositories end up pulling the same changes.

       Similarly, passing --rev to "hg clone" will fail to use any
       hardlinks, falling back to a complete copy of the source
       repository.

       This command lets you recreate those hardlinks and reclaim that
       wasted space.

       This repository will be relinked to share space with ORIGIN,
       which must be on the same local disk. If ORIGIN is omitted, looks
       for "default-relink", then "default", in [paths].

       Do not attempt any read operations on this repository while the
       command is running. (Both repositories will be locked against
       writes.)

   schemes
       extend schemes with shortcuts to repository swarms

       This extension allows you to specify shortcuts for parent URLs
       with a lot of repositories to act like a scheme, for example:

       [schemes]
       py = http://code.python.org/hg/

       After that you can use it like:

       hg clone py://trunk/

       Additionally there is support for some more complex schemas, for
       example used by Google Code:

       [schemes]
       gcode = http://{1}.googlecode.com/hg/

       The syntax is taken from Mercurial templates, and you have
       unlimited number of variables, starting with {1} and continuing
       with {2}, {3} and so on. This variables will receive parts of URL
       supplied, split by /. Anything not specified as {part} will be
       just appended to an URL.

       For convenience, the extension adds these schemes by default:

       [schemes]
       py = http://hg.python.org/
       bb = https://bitbucket.org/
       bb+ssh = ssh://hg@bitbucket.org/
       gcode = https://{1}.googlecode.com/hg/
       kiln = https://{1}.kilnhg.com/Repo/

       You can override a predefined scheme by defining a new scheme
       with the same name.

   share
       share a common history between several working directories

   Commands
   share
       hg share [-U] SOURCE [DEST]

       Initialize a new repository and working directory that shares its
       history with another repository.

       Note   using rollback or extensions that destroy/modify history
              (mq, rebase, etc.) can cause considerable confusion with
              shared clones. In particular, if two shared clones are
              both updated to the same changeset, and one of them
              destroys that changeset with rollback, the other clone
              will suddenly stop working: all operations will fail with
              "abort: working directory has unknown parent". The only
              known workaround is to use debugsetparents on the broken
              clone to reset it to a changeset that still exists (e.g.
              tip).

       Options:

       -U, --noupdate
              do not create a working copy

   unshare
       hg unshare

       Copy the store data to the repo and remove the sharedpath data.

   transplant
       command to transplant changesets from another branch

       This extension allows you to transplant changes to another parent
       revision, possibly in another repository. The transplant is done
       using 'diff' patches.

       Transplanted patches are recorded in .hg/transplant/transplants,
       as a map from a changeset hash to its hash in the source
       repository.

   Commands
   transplant
       hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...

       Selected changesets will be applied on top of the current working
       directory with the log of the original changeset. The changesets
       are copied and will thus appear twice in the history with
       different identities.

       Consider using the graft command if everything is inside the same
       repository - it will use merges and will usually give a better
       result.  Use the rebase extension if the changesets are
       unpublished and you want to move them instead of copying them.

       If --log is specified, log messages will have a comment appended
       of the form:

       (transplanted from CHANGESETHASH)

       You can rewrite the changelog message with the --filter option.
       Its argument will be invoked with the current changelog message
       as $1 and the patch as $2.

       --source/-s specifies another repository to use for selecting
       changesets, just as if it temporarily had been pulled.  If
       --branch/-b is specified, these revisions will be used as heads
       when deciding which changsets to transplant, just as if only
       these revisions had been pulled.  If --all/-a is specified, all
       the revisions up to the heads specified with --branch will be
       transplanted.

       Example:

       • transplant all changes up to REV on top of your current
         revision:

         hg transplant --branch REV --all

       You can optionally mark selected transplanted changesets as merge
       changesets. You will not be prompted to transplant any ancestors
       of a merged transplant, and you can merge descendants of them
       normally instead of transplanting them.

       Merge changesets may be transplanted directly by specifying the
       proper parent changeset by calling hg transplant --parent.

       If no merges or revisions are provided, hg transplant will start
       an interactive changeset browser.

       If a changeset application fails, you can fix the merge by hand
       and then resume where you left off by calling hg transplant
       --continue/-c.

       Options:

       -s, --source
              transplant changesets from REPO

       -b, --branch
              use this source changeset as head

       -a, --all
              pull all changesets up to the --branch revisions

       -p, --prune
              skip over REV

       -m, --merge
              merge at REV

       --parent
              parent to choose when transplanting merge

       -e, --edit
              invoke editor on commit messages

       --log  append transplant info to log message

       -c, --continue
              continue last transplant session after fixing conflicts

       --filter
              filter changesets through command

   win32mbcs
       allow the use of MBCS paths with problematic encodings

       Some MBCS encodings are not good for some path operations (i.e.
       splitting path, case conversion, etc.) with its encoded bytes. We
       call such a encoding (i.e. shift_jis and big5) as "problematic
       encoding".  This extension can be used to fix the issue with
       those encodings by wrapping some functions to convert to Unicode
       string before path operation.

       This extension is useful for:

       • Japanese Windows users using shift_jis encoding.

       • Chinese Windows users using big5 encoding.

       • All users who use a repository with one of problematic
         encodings on case-insensitive file system.

       This extension is not needed for:

       • Any user who use only ASCII chars in path.

       • Any user who do not use any of problematic encodings.

       Note that there are some limitations on using this extension:

       • You should use single encoding in one repository.

       • If the repository path ends with 0x5c, .hg/hgrc cannot be read.

       • win32mbcs is not compatible with fixutf8 extension.

       By default, win32mbcs uses encoding.encoding decided by
       Mercurial.  You can specify the encoding by config option:

       [win32mbcs]
       encoding = sjis

       It is useful for the users who want to commit with UTF-8 log
       message.

   win32text
       perform automatic newline conversion

          Deprecation: The win32text extension requires each user to
          configure the extension again and again for each clone since
          the configuration is not copied when cloning.

          We have therefore made the eol as an alternative. The eol uses
          a version controlled file for its configuration and each clone
          will therefore use the right settings from the start.

       To perform automatic newline conversion, use:

       [extensions]
       win32text =
       [encode]
       ** = cleverencode:
       # or ** = macencode:

       [decode]
       ** = cleverdecode:
       # or ** = macdecode:

       If not doing conversion, to make sure you do not commit CRLF/CR
       by accident:

       [hooks]
       pretxncommit.crlf = python:hgext.win32text.forbidcrlf
       # or pretxncommit.cr = python:hgext.win32text.forbidcr

       To do the same check on a server to prevent CRLF/CR from being
       pushed or pulled:

       [hooks]
       pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
       # or pretxnchangegroup.cr = python:hgext.win32text.forbidcr

   zeroconf
       discover and advertise repositories on the local network

       Zeroconf-enabled repositories will be announced in a network
       without the need to configure a server or a service. They can be
       discovered without knowing their actual IP address.

       To allow other people to discover your repository using run hg
       serve in your repository:

       $ cd test
       $ hg serve

       You can discover Zeroconf-enabled repositories by running hg
       paths:

       $ hg paths
       zc-test = http://example.com:8000/test

FILES         top

       /etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc

              This file contains defaults and configuration. Values in
              .hg/hgrc override those in $HOME/.hgrc, and these override
              settings made in the global /etc/mercurial/hgrc
              configuration.  See hgrc(5) for details of the contents
              and format of these files.

       .hgignore

              This file contains regular expressions (one per line) that
              describe file names that should be ignored by hg. For
              details, see hgignore(5).

       .hgsub

              This file defines the locations of all subrepositories,
              and tells where the subrepository checkouts came from. For
              details, see hg help subrepos.

       .hgsubstate

              This file is where Mercurial stores all nested repository
              states. NB: This file should not be edited manually.

       .hgtags

              This file contains changeset hash values and text tag
              names (one of each separated by spaces) that correspond to
              tagged versions of the repository contents. The file
              content is encoded using UTF-8.

       .hg/last-message.txt

              This file is used by hg commit to store a backup of the
              commit message in case the commit fails.

       .hg/localtags

              This file can be used to define local tags which are not
              shared among repositories. The file format is the same as
              for .hgtags, but it is encoded using the local system
              encoding.

       Some commands (e.g. revert) produce backup files ending in .orig,
       if the .orig file already exists and is not tracked by Mercurial,
       it will be overwritten.
