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. | ||

34 | depends on CONFIG_AR | ||
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. | ||
40 | |||
41 | config CONFIG_BUNZIP2 | ||
42 | bool "bunzip2" | ||
43 | default n | ||
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. | ||
56 | |||
57 | config CONFIG_CPIO | ||
58 | bool "cpio" | ||
59 | default n | ||
60 | help | ||
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. | ||
67 | |||
68 | Unless you have a specific application which requires cpio, you should | ||
69 | probably say N here. | ||

71 | config CONFIG_DPKG | ||

74 | help | ||
75 | dpkg is a medium-level tool to install, build, remove and manage Debian packages. | ||
76 | |||
77 | This implementation of dpkg has a number of limitations, you should use the | ||
78 | official dpkg if possible. | ||
79 | |||
80 | config CONFIG_DPKG_DEB | ||
81 | bool "dpkg_deb" | ||
82 | default n | ||
83 | help | ||
84 | dpkg-deb packs, unpacks and provides information about Debian archives. | ||
85 | |||
86 | This implementation of dpkg-deb cannot pack archives. | ||
87 | |||
88 | Unless you have a specific application which requires dpkg-deb, you should | ||

95 | help | ||
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. | ||

105 | You can use the `-t' option to test the integrity of | ||
106 | an archive, without decompressing it. | ||
