10 bool "Make tar, rpm, modprobe etc understand .xz data"
11 default BUSYBOX_DEFAULT_FEATURE_SEAMLESS_XZ
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"

37 Make tar, rpm, modprobe etc understand .Z 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. In practice, it is used exclusively
45 for object module archives used by compilers.
47 On an x86 system, the ar applet adds about 1K.
49 Unless you have a specific application which requires ar, you should
50 probably say N here: most compilers come with their own ar utility.
52 config BUSYBOX_CONFIG_FEATURE_AR_LONG_FILENAMES
53 bool "Support for long filenames (not needed for debs)"
54 default BUSYBOX_DEFAULT_FEATURE_AR_LONG_FILENAMES
55 depends on BUSYBOX_CONFIG_AR
57 By default the ar format can only store the first 15 characters
58 of the filename, this option removes that limitation.
59 It supports the GNU ar long filename method which moves multiple long
60 filenames into a the data section of a new ar entry.
62 config BUSYBOX_CONFIG_FEATURE_AR_CREATE
63 bool "Support archive creation"
64 default BUSYBOX_DEFAULT_FEATURE_AR_CREATE

78 gunzip is used to decompress archives created by gzip.
79 You can use the `-t' option to test the integrity of

88 config BUSYBOX_CONFIG_BUNZIP2
90 default BUSYBOX_DEFAULT_BUNZIP2
92 bunzip2 is a compression utility using the Burrows-Wheeler block
93 sorting text compression algorithm, and Huffman coding. Compression
94 is generally considerably better than that achieved by more
95 conventional LZ77/LZ78-based compressors, and approaches the
96 performance of the PPM family of statistical compressors.
98 Unless you have a specific application which requires bunzip2, you
99 should probably say N here.
100 config BUSYBOX_CONFIG_UNLZMA
102 default BUSYBOX_DEFAULT_UNLZMA

105 compression algorithm, and range coding. Compression

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

129 default BUSYBOX_DEFAULT_UNXZ
131 unxz is a unlzma successor.
133 config BUSYBOX_CONFIG_XZ
134 bool "Provide xz alias which supports only unpacking"
135 default BUSYBOX_DEFAULT_XZ
136 depends on BUSYBOX_CONFIG_UNXZ

142 default BUSYBOX_DEFAULT_BZIP2
144 bzip2 is a compression utility using the Burrows-Wheeler block
145 sorting text compression algorithm, and Huffman coding. Compression

147 conventional LZ77/LZ78-based compressors, and approaches the
148 performance of the PPM family of statistical compressors.
150 Unless you have a specific application which requires bzip2, you
151 should probably say N here.
152 config BUSYBOX_CONFIG_CPIO
154 default BUSYBOX_DEFAULT_CPIO
156 cpio is an archival utility program used to create, modify, and
157 extract contents from archives.

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