8 config BUSYBOX_CONFIG_AR
9 bool "ar"
10 default n
11 help
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
18 extraction.
19
20 The stored filename is limited to 15 characters. (for more information
21 see long filename support).
22 ar has 60 bytes of overheads for every stored file.
23
24 This implementation of ar can extract archives, it cannot create or
25 modify them.
26 On an x86 system, the ar applet adds about 1K.
27
28 Unless you have a specific application which requires ar, you should
29 probably say N here.

35 help
36 By default the ar format can only store the first 15 characters of the
37 filename, this option removes that limitation.
38 It supports the GNU ar long filename method which moves multiple long
39 filenames into a the data section of a new ar entry.

41 config BUSYBOX_CONFIG_BUNZIP2
42 bool "bunzip2"
43 default y
44 help
45 bunzip2 is a compression utility using the Burrows-Wheeler block
46 sorting text compression algorithm, and Huffman coding. Compression
47 is generally considerably better than that achieved by more
48 conventional LZ77/LZ78-based compressors, and approaches the
49 performance of the PPM family of statistical compressors.
50
51 The BusyBox bunzip2 applet is limited to de-compression only.
52 On an x86 system, this applet adds about 11K.
53
54 Unless you have a specific application which requires bunzip2, you
55 should probably say N here.

61 cpio is an archival utility program used to create, modify, and extract
62 contents from archives.
63 cpio has 110 bytes of overheads for every stored file.
64
65 This implementation of cpio can extract cpio archives created in the
66 "newc" or "crc" format, it cannot create or modify them.

96 This reduces dpkg-deb to the equivalent of "ar -p <deb> data.tar.gz | tar -zx".
97 However it saves space as none of the extra dpkg-deb, ar or tar options are
98 needed, they are linked to internally.
