The file is an ar archive with a magic value of !<arch>. The file
names might contain a trailing slash (since dpkg 1.15.6).
The first member is named debian-split and contains a series of
lines, separated by newlines. Currently eight lines are present:
· The format version number, 2.1 at the time this manual page was
· The package name.
· The package version.
· The md5sum of the package.
· The total size of the package.
· The maximum part size.
· The current part number, followed by a slash and the total amount
of parts (as in ‘1/10’).
· The package architecture (since dpkg 1.16.1).
Programs which read multi-part archives should be prepared for the
minor format version number to be increased and additional lines to
be present, and should ignore these if this is the case.
If the major format version number has changed, an incompatible
change has been made and the program should stop. If it has not, then
the program should be able to safely continue, unless it encounters
an unexpected member in the archive (except at the end), as described
The second, last required member is named data.N, where N denotes the
part number. It contains the raw part data.
These members must occur in this exact order. Current implementations
should ignore any additional members after data.N. Further members
may be defined in the future, and (if possible) will be placed after
