NAME         top

       dsc - Debian source packages' control file format

SYNOPSIS         top


DESCRIPTION         top

       Each Debian source package is composed of a .dsc control file,
       which contains a number of fields.  Each field begins with a tag,
       such as Source or Binary (case insensitive), followed by a colon,
       and the body of the field.  Fields are delimited only by field
       tags.  In other words, field text may be multiple lines in
       length, but the installation tools will generally join lines when
       processing the body of the field (except in case of the multiline
       fields Package-List, Files, Checksums-Sha1 and Checksums-Sha256,
       see below).

       The control data might be enclosed in an OpenPGP ASCII Armored
       signature, as specified in RFC4880.

FIELDS         top

       Format: format-version (required)
              The value of this field declares the format version of the
              source package.  The field value is used by programs
              acting on a source package to interpret the list of files
              in the source package and determine how to unpack it.  The
              syntax of the field value is a numeric major revision
              (“0-9”), a period (“.”), a numeric minor revision (“0-9”),
              and then an optional subtype after whitespace (“ \t”),
              which if specified is a lowercase alphanumeric (“a-z0-9”)
              word in parentheses (“()”).  The subtype is optional in
              the syntax but may be mandatory for particular source
              format revisions.

              The source formats currently supported by dpkg are 1.0,
              2.0, 3.0 (native), 3.0 (quilt), 3.0 (git), 3.0 (bzr) and
              3.0 (custom).  See dpkg-source(1) for their description.

       Source: source-name (required)
              The value of this field determines the package name, and
              is used to generate file names by most installation tools.

       Binary: binary-package-list
              This folded field lists binary packages which this source
              package can produce, separated by commas.

              This field has now been superseded by the Package-List
              field, which gives enough information about what binary
              packages are produced on which architecture, build-profile
              and other involved restrictions.

       Architecture: arch-list (recommended)
              A list of architectures and architecture wildcards
              separated by spaces which specify the type of hardware
              this package can be compiled for.  Common architecture
              names and architecture wildcards are amd64, armel, i386,
              linux-any, any-amd64, etc.

              Note that the all value is meant for packages that are
              architecture independent, and any for packages that are
              architecture dependent.  The list may include (or consist
              solely of) the special value all.  When the list contains
              the architecture wildcard any, the only other value
              allowed in the list is all.

              The field value is generally generated from Architecture
              fields from in the debian/control in the source package.

       Version: version-string (required)
              Typically, this is the original package's version number
              in whatever form the program's author uses.  It may also
              include a Debian revision number (for non-native
              packages).  The exact format and sorting algorithm are
              described in deb-version(7).

       Origin: name
              The name of the distribution this package is originating

       Maintainer: fullname-email (recommended)
              Should be in the format “Joe Bloggs <jbloggs@foo.com>”,
              and is typically the person who created the package, as
              opposed to the author of the software that was packaged.

       Uploaders: fullname-email-list
              Lists all the names and email addresses of co-maintainers
              of the package, in the same format as the Maintainer
              field.  Multiple co-maintainers should be separated by a

       Description short-description
              The format for the source package description is a short
              brief summary on the first line (after the Description
              field).  The following lines should be used as a longer,
              more detailed description.  Each line of the long
              description must be preceded by a space, and blank lines
              in the long description must contain a single ‘.’
              following the preceding space.

       Homepage: url
              The upstream project home page url.

       Standards-Version: version-string (recommended)
              This documents the most recent version of the distribution
              policy standards this package complies with.

       Vcs-Browser: url
              The url of a web interface to browse the Version Control
              System repository.

       Vcs-Arch: url
       Vcs-Bzr: url
       Vcs-Cvs: url
       Vcs-Darcs: url
       Vcs-Git: url
       Vcs-Hg: url
       Vcs-Mtn: url
       Vcs-Svn: url
              These fields declare the url of the Version Control System
              repository used to maintain this package.  See
              deb-src-control(5) for more details.

       Testsuite: name-list
              This field declares that the source package contains the
              specified test suites.  The value is a comma-separated
              list of test suites.  If the autopkgtest value is present,
              a debian/tests/control is expected to be present, if the
              file is present but not the value, then dpkg-source will
              automatically add it, preserving previous values.

       Testsuite-Triggers: package-list
              This field declares the comma-separated union of all test
              dependencies (Depends fields in debian/tests/control
              file), with all restrictions removed, and OR dependencies
              flattened (that is, converted to separate AND
              relationships), except for binaries generated by this
              source package and its meta-dependency equivalent @.

              Rationale: this field is needed because otherwise to be
              able to get the test dependencies, each source package
              would need to be unpacked.

       Build-Depends: package-list
       Build-Depends-Arch: package-list
       Build-Depends-Indep: package-list
       Build-Conflicts: package-list
       Build-Conflicts-Arch: package-list
       Build-Conflicts-Indep: package-list
              These fields declare relationships between the source
              package and packages used to build it.  They are discussed
              in the deb-src-control(5) manpage.

        package package-type section priority key-value-list
              This multiline field contains a list of binary packages
              generated by this source package.

              The package is the binary package name.

              The package-type is the binary package type, usually deb,
              another common value is udeb.

              The section and priority match the binary package fields
              of the same name.

              The key-value-list is a space separated key=value list,
              and the currently known optional keys are:

              arch   The architecture restriction from the binary
                     package Architecture field, with spaces converted
                     to ‘,’.

                     The normalized build-profile restriction formula
                     from the binary package Build-Profile field, with
                     ORs converted to ‘+’ and ANDs to ‘,’.

                     If the binary package is essential, this key will
                     contain the value of the Essential field, that is a
                     yes value.

       Files: (required)
       Checksums-Sha1: (required)
       Checksums-Sha256: (required)
        checksum size filename
              These multiline fields contain a list of files with a
              checksum and size for each one.  These fields have the
              same syntax and differ only in the checksum algorithm
              used: MD5 for Files, SHA-1 for Checksums-Sha1 and SHA-256
              for Checksums-Sha256.

              The first line of the field value (the part on the same
              line as the field name followed by a colon) is always
              empty.  The content of the field is expressed as
              continuation lines, one line per file.  Each line consists
              of the checksum, a space, the file size, a space, and the
              file name.

              These fields list all files that make up the source
              package.  The list of files in these fields must match the
              list of files in the other related fields.

BUGS         top

       The Format field conflates the format for the .dsc file itself
       and the format of the extracted source package.
