Eric Andersen53601822002-12-05 21:12:42 +0000[diff] [blame]12 ar is an archival utility program used to create, modify, and
13 extract contents from archives. An archive is a single file holding
14 a collection of other files in a structure that makes it possible to
15 retrieve the original individual files (called archive members).
16 The original files' contents, mode (permissions), timestamp, owner,
17 and group are preserved in the archive, and can be restored on
Glenn L McGrath0337c462002-12-06 22:40:54 +0000[diff] [blame]18 extraction.
19 The stored filename is limited to 15 characters. (for more information
20 see long filename support).
21 ar has 60 bytes of overheads for every stored file.
22
23 This implementation of ar can extract archives, it cannot create or
24 modify them.
Eric Andersen53601822002-12-05 21:12:42 +0000[diff] [blame]25 On an x86 system, the ar applet adds about XXX bytes.
26
27 Unless you have a specific application which requires ar, you should
28 probably say N here.

33 depends on CONFIG_AR
34 help
Glenn L McGrath0337c462002-12-06 22:40:54 +0000[diff] [blame]35 By default the ar format can only store the first 15 characters of the
36 filename, this option removes that limitation.
37 It supports the GNU ar long filename method which moves multiple long
38 filenames into a the data section of a new ar entry.

43 help
Eric Andersen53601822002-12-05 21:12:42 +0000[diff] [blame]44 bunzip2 is an compression utility using the Burrows-Wheeler block
45 sorting text compression algorithm, and Huffman coding. Compression
46 is generally considerably better than that achieved by more
47 conventional LZ77/LZ78-based compressors, and approaches the
48 performance of the PPM family of statistical compressors.

Glenn L McGrath0337c462002-12-06 22:40:54 +0000[diff] [blame]95 This reduced dpkg-deb to the equivalent of "ar -p <deb> data.tar.gz | tar -zx".
96 However it saves space as none of the extra dpkg-deb, ar or tar options are
97 needed, they are linked to internally.

114 with bzip2 instead of gzip.
115

117 use an internal control.tar.bz2 or data.tar.bz2.
