NAME         top

       deb-old - old style Debian binary package format

SYNOPSIS         top


DESCRIPTION         top

       The .deb format is the Debian binary package file format.  This
       manual page describes the old format, used before Debian 0.93.
       Please see deb(5) for details of the new format.

FORMAT         top

       The file is two lines of format information as ASCII text,
       followed by two concatenated gzipped ustar files.

       The first line is the format version number padded to 8 digits,
       and is 0.939000 for all old-format archives.

       The second line is a decimal string (without leading zeroes)
       giving the length of the first gzipped tarfile.

       Each of these lines is terminated with a single newline

       The first tarfile contains the control information, as a series
       of ordinary files.  The file control must be present, as it
       contains the core control information.

       In some very old archives, the files in the control tarfile may
       optionally be in a DEBIAN subdirectory.  In that case, the DEBIAN
       subdirectory will be in the control tarfile too, and the control
       tarfile will have only files in that directory.  Optionally the
       control tarfile may contain an entry for ‘.’, that is, the
       current directory.

       The second gzipped tarfile is the filesystem archive, containing
       pathnames relative to the root directory of the system to be
       installed on.  The pathnames do not have leading slashes.
