13 Make tar, rpm, modprobe etc understand .xz data.
15 config BUSYBOX_CONFIG_FEATURE_SEAMLESS_LZMA
16 bool "Make tar, rpm, modprobe etc understand .lzma data"

39 config BUSYBOX_CONFIG_AR
41 default BUSYBOX_DEFAULT_AR # needs to be improved to be able to replace binutils ar
43 ar is an archival utility program used to create, modify, and
44 extract contents from archives. An archive is a single file holding
45 a collection of other files in a structure that makes it possible to
46 retrieve the original individual files (called archive members).
47 The original files' contents, mode (permissions), timestamp, owner,
48 and group are preserved in the archive, and can be restored on
51 The stored filename is limited to 15 characters. (for more information
52 see long filename support).
53 ar has 60 bytes of overheads for every stored file.
55 This implementation of ar can extract archives, it cannot create or
57 On an x86 system, the ar applet adds about 1K.
59 Unless you have a specific application which requires ar, you should
62 config BUSYBOX_CONFIG_FEATURE_AR_LONG_FILENAMES
63 bool "Support for long filenames (not needed for debs)"
64 default BUSYBOX_DEFAULT_FEATURE_AR_LONG_FILENAMES
65 depends on BUSYBOX_CONFIG_AR
67 By default the ar format can only store the first 15 characters
68 of the filename, this option removes that limitation.
69 It supports the GNU ar long filename method which moves multiple long
70 filenames into a the data section of a new ar entry.
72 config BUSYBOX_CONFIG_FEATURE_AR_CREATE
73 bool "Support archive creation"
74 default BUSYBOX_DEFAULT_FEATURE_AR_CREATE

80 default BUSYBOX_DEFAULT_UNCOMPRESS
82 uncompress is used to decompress archives created by compress.
83 Not much used anymore, replaced by gzip/gunzip.
84 config BUSYBOX_CONFIG_GUNZIP
86 default BUSYBOX_DEFAULT_GUNZIP

89 You can use the `-t' option to test the integrity of
90 an archive, without decompressing it.
91 config BUSYBOX_CONFIG_BUNZIP2
93 default BUSYBOX_DEFAULT_BUNZIP2
95 bunzip2 is a compression utility using the Burrows-Wheeler block
96 sorting text compression algorithm, and Huffman coding. Compression
97 is generally considerably better than that achieved by more
98 conventional LZ77/LZ78-based compressors, and approaches the
99 performance of the PPM family of statistical compressors.
101 Unless you have a specific application which requires bunzip2, you
102 should probably say N here.
103 config BUSYBOX_CONFIG_UNLZMA
105 default BUSYBOX_DEFAULT_UNLZMA
107 unlzma is a compression utility using the Lempel-Ziv-Markov chain
108 compression algorithm, and range coding. Compression

124 bool "Provide lzma alias which supports only unpacking"
125 default BUSYBOX_DEFAULT_LZMA
126 depends on BUSYBOX_CONFIG_UNLZMA
128 Enable this option if you want commands like "lzma -d" to work.
129 IOW: you'll get lzma applet, but it will always require -d option.

132 default BUSYBOX_DEFAULT_UNXZ
134 unxz is a unlzma successor.
136 config BUSYBOX_CONFIG_XZ

143 config BUSYBOX_CONFIG_BZIP2
145 default BUSYBOX_DEFAULT_BZIP2
147 bzip2 is a compression utility using the Burrows-Wheeler block
148 sorting text compression algorithm, and Huffman coding. Compression
149 is generally considerably better than that achieved by more
150 conventional LZ77/LZ78-based compressors, and approaches the
151 performance of the PPM family of statistical compressors.
153 Unless you have a specific application which requires bzip2, you
154 should probably say N here.
155 config BUSYBOX_CONFIG_CPIO
157 default BUSYBOX_DEFAULT_CPIO
159 cpio is an archival utility program used to create, modify, and
160 extract contents from archives.
161 cpio has 110 bytes of overheads for every stored file.
163 This implementation of cpio can extract cpio archives created in the
164 "newc" or "crc" format, it cannot create or modify them.

170 bool "Support for archive creation"
171 default BUSYBOX_DEFAULT_FEATURE_CPIO_O
172 depends on BUSYBOX_CONFIG_CPIO

206 bool "Extract only (-x)"
207 default BUSYBOX_DEFAULT_FEATURE_DPKG_DEB_EXTRACT_ONLY
208 depends on BUSYBOX_CONFIG_DPKG_DEB
210 This reduces dpkg-deb to the equivalent of
211 "ar -p <deb> data.tar.gz | tar -zx". However it saves space as none
212 of the extra dpkg-deb, ar or tar options are needed, they are linked
