NAME

       deb-old - old style Debian binary package format

SYNOPSIS

       filename.deb

DESCRIPTION

       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

       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 character.

       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.
