8 | 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. | ||
30 | |||
31 | config FEATURE_AR_LONG_FILENAMES | ||
32 | bool "Enable support for long filenames (not need for debs)" | ||
33 | default n | ||
34 | depends on 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 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 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. | ||
70 | |||
71 | config DPKG | ||
72 | bool "dpkg" | ||
73 | default n | ||
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 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 | ||
89 | probably say N here. | ||
90 | |||
91 | config FEATURE_DPKG_DEB_EXTRACT_ONLY | ||
92 | bool "extract only (-x)" | ||
93 | default n | ||
94 | depends on DPKG_DEB | ||
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. | ||
99 | |||
100 | config GUNZIP | ||
101 | bool "gunzip" | ||
102 | default n | ||
103 | help | ||
104 | gunzip is used to decompress archives created by gzip. | ||
105 | You can use the `-t' option to test the integrity of | ||
106 | an archive, without decompressing it. | ||
107 | |||
108 | config FEATURE_GUNZIP_UNCOMPRESS | ||
109 | bool "Uncompress support" | ||
110 | default n | ||
111 | depends on GUNZIP | ||
112 | help | ||
113 | Enable if you want gunzip to have the ability to decompress | ||
114 | archives created by the program compress (not much | ||
115 | used anymore). | ||
116 | |||
117 | config GZIP | ||
118 | bool "gzip" | ||
119 | default n | ||
120 | help | ||
121 | gzip is used to compress files. | ||
122 | It's probably the most widely used UNIX compression program. | ||
123 | |||
124 | config RPM2CPIO | ||
125 | bool "rpm2cpio" | ||
126 | default n | ||
127 | help | ||
128 | Converts an RPM file into a CPIO archive. | ||
129 | |||
130 | config RPM | ||
131 | bool "rpm" | ||
132 | default n | ||
133 | help | ||
134 | Mini RPM applet - queries and extracts RPM packages. | ||
135 | |||
136 | config TAR | ||
137 | bool "tar" | ||
138 | default n | ||
139 | help | ||
140 | tar is an archiving program. It's commonly used with gzip to | ||
141 | create compressed archives. It's probably the most widely used | ||
142 | UNIX archive program. | ||
143 | |||
144 | config FEATURE_TAR_CREATE | ||
145 | bool "Enable archive creation" | ||
146 | default y | ||

150 | tar archives using the `-c' option. | ||

158 | archives compressed with bzip2. | ||

163 | depends on TAR | ||
164 | help | ||
165 | If you enable this option you'll be able to extract | ||
166 | archives compressed with lzma. | ||
167 | |||
168 | config FEATURE_TAR_FROM | ||
169 | bool "Enable -X (exclude from) and -T (include from) options)" | ||
170 | default n | ||
171 | depends on TAR | ||
172 | help | ||
173 | If you enable this option you'll be able to specify | ||
174 | a list of files to include or exclude from an archive. | ||
175 | |||
176 | config FEATURE_TAR_GZIP | ||
177 | bool "Enable -z option" | ||
178 | default y | ||
179 | depends on TAR | ||
180 | help | ||
181 | If you enable this option tar will be able to call gzip, | ||
182 | when creating or extracting tar gziped archives. | ||
183 | |||
184 | config FEATURE_TAR_COMPRESS | ||
185 | bool "Enable -Z option" | ||
186 | default n | ||
187 | depends on TAR | ||
188 | help | ||
189 | If you enable this option tar will be able to call uncompress, | ||
190 | when extracting .tar.Z archives. | ||
191 | |||
192 | config FEATURE_TAR_OLDGNU_COMPATIBILITY | ||
193 | bool "Enable support for old tar header format" | ||
194 | default N | ||
195 | depends on TAR | ||
196 | help | ||
197 | This option is required to unpack archives created in | ||
198 | the old GNU format; help to kill this old format by | ||
199 | repacking your ancient archives with the new format. | ||
200 | |||
201 | config FEATURE_TAR_GNU_EXTENSIONS | ||
202 | bool "Enable support for some GNU tar extensions" | ||
203 | default y | ||

222 | |||
223 | config UNLZMA | ||
224 | bool "unlzma" | ||
225 | default n | ||
226 | help | ||
227 | unlzma is a compression utility using the Lempel-Ziv-Markov chain | ||
228 | compression algorithm, and range coding. Compression | ||
229 | is generally considerably better than that achieved by the bzip2 | ||
230 | compressors. | ||
231 | |||
232 | The BusyBox unlzma applet is limited to de-compression only. | ||
233 | On an x86 system, this applet adds about 4K. | ||
234 | |||
235 | Unless you have a specific application which requires unlzma, you | ||
236 | should probably say N here. | ||
237 | |||
238 | config FEATURE_LZMA_FAST | ||
239 | bool "Optimze unlzma for speed" | ||
240 | default n | ||
241 | depends on UNLZMA | ||
242 | help | ||
243 | This option reduces decompression time by about 33% at the cost of | ||
244 | a 2K bigger binary. | ||
245 | |||
246 | config UNZIP | ||
247 | bool "unzip" | ||
248 | default n | ||
249 | help | ||
250 | unzip will list or extract files from a ZIP archive, | ||
251 | commonly found on DOS/WIN systems. The default behavior | ||
252 | (with no options) is to extract the archive into the | ||
253 | current directory. Use the `-d' option to extract to a | ||
254 | directory of your choice. | ||
