+ help
+ ar is an archival utility program used to create, modify, and
+ extract contents from archives. An archive is a single file holding
+ a collection of other files in a structure that makes it possible to
+ retrieve the original individual files (called archive members).
+ The original files' contents, mode (permissions), timestamp, owner,
+ and group are preserved in the archive, and can be restored on
+ extraction.
+
+ The stored filename is limited to 15 characters. (for more information
+ see long filename support).
+ ar has 60 bytes of overheads for every stored file.
+
+ This implementation of ar can extract archives, it cannot create or
+ modify them.
+ On an x86 system, the ar applet adds about 1K.
+
+ Unless you have a specific application which requires ar, you should
+ probably say N here.
+
+config FEATURE_AR_LONG_FILENAMES
+ bool "Support for long filenames (not needed for debs)"
+ default n
+ depends on AR
+ help
+ By default the ar format can only store the first 15 characters
+ of the filename, this option removes that limitation.
+ It supports the GNU ar long filename method which moves multiple long
+ filenames into a the data section of a new ar entry.

+ depends on AR
+ help
+ This enables archive creation (-c and -r) with busybox ar.
+
+config BUNZIP2
+ bool "bunzip2"
+ default n
+ help
+ bunzip2 is a compression utility using the Burrows-Wheeler block
+ sorting text compression algorithm, and Huffman coding. Compression
+ is generally considerably better than that achieved by more
+ conventional LZ77/LZ78-based compressors, and approaches the
+ performance of the PPM family of statistical compressors.
+
+ Unless you have a specific application which requires bunzip2, you
+ should probably say N here.

+ cpio has 110 bytes of overheads for every stored file.
+
+ This implementation of cpio can extract cpio archives created in the

+
+ Unless you have a specific application which requires cpio, you

+
+config FEATURE_CPIO_O

+ This implementation of cpio can create cpio archives in the "newc"
+ format only.

+ default n
+ depends on FEATURE_CPIO_O
+ help
+ Passthrough mode. Rarely used.

+config DPKG
+ bool "dpkg"

+ select FEATURE_SEAMLESS_GZ
+ help
+ dpkg is a medium-level tool to install, build, remove and manage
+ Debian packages.
+
+ This implementation of dpkg has a number of limitations,
+ you should use the official dpkg if possible.
+
+config DPKG_DEB
+ bool "dpkg_deb"
+ default n
+ select FEATURE_SEAMLESS_GZ
+ help
+ dpkg-deb unpacks and provides information about Debian archives.

+ say N here.
+
+config FEATURE_DPKG_DEB_EXTRACT_ONLY
+ bool "Extract only (-x)"
+ default n
+ depends on DPKG_DEB
+ help
+ This reduces dpkg-deb to the equivalent of
+ "ar -p <deb> data.tar.gz | tar -zx". However it saves space as none
+ of the extra dpkg-deb, ar or tar options are needed, they are linked
+ to internally.
+
+config GUNZIP
+ bool "gunzip"
+ default n
+ help
+ gunzip is used to decompress archives created by gzip.
+ You can use the `-t' option to test the integrity of
+ an archive, without decompressing it.
+
+config GZIP
+ bool "gzip"
+ default n
+ help
+ gzip is used to compress files.
+ It's probably the most widely used UNIX compression program.
+
+config FEATURE_GZIP_LONG_OPTIONS

+config LZOP_COMPR_HIGH
+ bool "lzop complession levels 7,8,9 (not very useful)"
+ default n
+ depends on LZOP
+ help
+ High levels (7,8,9) of lzop compression. These levels
+ are actually slower than gzip at equivalent compression ratios
+ and take up 3.2K of code.

+ create compressed archives. It's probably the most widely used
+ UNIX archive program.

+
+config FEATURE_TAR_OLDSUN_COMPATIBILITY
+ bool "Enable untarring of tarballs with checksums produced by buggy Sun tar"
+ default N
+ depends on TAR || DPKG
+ help
+ This option is required to unpack archives created by some old
+ version of Sun's tar (it was calculating checksum using signed
+ arithmetic). It is said to be fixed in newer Sun tar, but "old"
+ tarballs still exist.
+
+config FEATURE_TAR_GNU_EXTENSIONS
+ bool "Support for GNU tar extensions (long filenames)"
+ default y
+ depends on TAR || DPKG

+ With this option busybox supports GNU long filenames and

+ (do not preserve time) option.
+
+config FEATURE_TAR_SELINUX
+ bool "Support for extracting SELinux labels"
+ default n
+ depends on TAR && SELINUX
+ help
+ With this option busybox supports restoring SELinux labels
+ when extracting files from tar archives.
+
+config UNCOMPRESS
+ bool "uncompress"
+ default n
+ help
+ uncompress is used to decompress archives created by compress.
+ Not much used anymore, replaced by gzip/gunzip.
+
+config UNLZMA
+ bool "unlzma"
+ default n
+ help
+ unlzma is a compression utility using the Lempel-Ziv-Markov chain
+ compression algorithm, and range coding. Compression
+ is generally considerably better than that achieved by the bzip2
