20 .TH deb\-old 5 "%RELEASE_DATE%" "%VERSION%" "dpkg suite"
23 deb\-old \- old style Debian binary package format
31 format is the Debian binary package file format. This manual page
34 format, used before Debian 0.93. Please see
36 for details of the new format.
39 The file is two lines of format information as ASCII text, followed by
40 two concatenated gzipped ustar files.
42 The first line is the format version number padded to 8 digits, and is
44 for all old-format archives.
46 The second line is a decimal string (without leading zeroes) giving
47 the length of the first gzipped tarfile.
49 Each of these lines is terminated with a single newline character.
51 The first tarfile contains the control information, as a series of
52 ordinary files. The file
54 must be present, as it contains the core control information.
56 In some very old archives, the files in the control tarfile may
59 subdirectory. In that case, the
61 subdirectory will be in the control tarfile too, and the control
62 tarfile will have only files in that directory. Optionally the
63 control tarfile may contain an entry for
65 that is, the current directory.
67 The second gzipped tarfile is the filesystem archive, containing
68 pathnames relative to the root directory of the system to be installed
69 on. The pathnames do not have leading slashes.
