deb-split(5)                      dpkg suite                      deb-split(5)

NAME
       deb-split - Debian multi-part binary package format

SYNOPSIS
       filename.deb

DESCRIPTION
       The  multi-part  .deb format is used to split big packages into smaller
       pieces to ease transport in small media.

FORMAT
       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:

       o   The format version number, 2.1 at the time  this  manual  page  was
           written.

       o   The package name.

       o   The package version.

       o   The md5sum of the package.

       o   The total size of the package.

       o   The maximum part size.

       o   The  current  part number, followed by a slash and the total amount
           of parts (as in '1/10').

       o   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
       below.

       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 these
       two.
