+config AR
+ bool "ar"
+ default n
+ 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 "Enable support for long filenames (not need 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.
+
+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.
+
+ The BusyBox bunzip2 applet is limited to de-compression only.
+ On an x86 system, this applet adds about 11K.
+
+ Unless you have a specific application which requires bunzip2, you
+ should probably say N here.
+
+config CPIO
+ bool "cpio"
+ default n
+ help
+ cpio is an archival utility program used to create, modify, and extract
+ contents from archives.
+ cpio has 110 bytes of overheads for every stored file.
+
+ This implementation of cpio can extract cpio archives created in the
+ "newc" or "crc" format, it cannot create or modify them.
+
+ Unless you have a specific application which requires cpio, you should
+ probably say N here.
+
+config DPKG
+ bool "dpkg"
+ default n
+ 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
+ help
+ dpkg-deb packs, unpacks and provides information about Debian archives.
+
+ This implementation of dpkg-deb cannot pack archives.
+
+ Unless you have a specific application which requires dpkg-deb, you should
+ probably 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 FEATURE_GUNZIP_UNCOMPRESS
+ bool "Uncompress support"
+ default n
+ depends on GUNZIP
+ help
+ Enable if you want gunzip to have the ability to decompress
+ archives created by the program compress (not much
+ used anymore).
+
+config GZIP
+ bool "gzip"
+ default n
+ help
+ gzip is used to compress files.
+ It's probably the most widely used UNIX compression program.
+
+config RPM2CPIO
+ bool "rpm2cpio"
+ default n
+ help
+ Converts an RPM file into a CPIO archive.
+
+config RPM
+ bool "rpm"
+ default n
+ help
+ Mini RPM applet - queries and extracts RPM packages.
+
+config TAR
+ bool "tar"
+ default n
+ help
+ tar is an archiving program. It's commonly used with gzip to
+ create compressed archives. It's probably the most widely used
+ UNIX archive program.
+
+config FEATURE_TAR_CREATE
+ bool "Enable archive creation"
+ default y
+ depends on TAR
+ help
+ If you enable this option you'll be able to create
+ tar archives using the `-c' option.
+
+config FEATURE_TAR_BZIP2
+ bool "Enable -j option to handle .tar.bz2 files"
+ default n
+ depends on TAR
+ help
+ If you enable this option you'll be able to extract
+ archives compressed with bzip2.
+
+config FEATURE_TAR_LZMA
+ bool "Enable -a option to handle .tar.lzma files"
+ default n
+ depends on TAR
+ help
+ If you enable this option you'll be able to extract
+ archives compressed with lzma.
+
+config FEATURE_TAR_FROM
+ bool "Enable -X (exclude from) and -T (include from) options)"
+ default n
+ depends on TAR
+ help
+ If you enable this option you'll be able to specify
+ a list of files to include or exclude from an archive.
+
+config FEATURE_TAR_GZIP
+ bool "Enable -z option"
+ default y
+ depends on TAR
+ help
+ If you enable this option tar will be able to call gzip,
+ when creating or extracting tar gziped archives.
+
+config FEATURE_TAR_COMPRESS
+ bool "Enable -Z option"
+ default n
+ depends on TAR
+ help
+ If you enable this option tar will be able to call uncompress,
+ when extracting .tar.Z archives.
+
+config FEATURE_TAR_OLDGNU_COMPATIBILITY
+ bool "Enable support for old tar header format"
+ default N
+ depends on TAR
+ help
+ This option is required to unpack archives created in
+ the old GNU format; help to kill this old format by
+ repacking your ancient archives with the new format.
+
+config FEATURE_TAR_GNU_EXTENSIONS
+ bool "Enable support for some GNU tar extensions"
+ default y
+ depends on TAR
+ help
+ With this option busybox supports GNU long filenames and
+ linknames.
+
+config FEATURE_TAR_LONG_OPTIONS
+ bool "Enable long options"
+ default n
+ depends on TAR && GETOPT_LONG
+ help
+ Enable use of long options, increases size by about 400 Bytes
+
+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
+ compressors.
+
+ The BusyBox unlzma applet is limited to de-compression only.
+ On an x86 system, this applet adds about 4K.
+
+ Unless you have a specific application which requires unlzma, you
+ should probably say N here.
+
+config FEATURE_LZMA_FAST
+ bool "Optimze unlzma for speed"
+ default n
+ depends on UNLZMA
+ help
+ This option reduces decompression time by about 33% at the cost of
+ a 2K bigger binary.
+
+config UNZIP
+ bool "unzip"
+ default n
+ help
+ unzip will list or extract files from a ZIP archive,
+ commonly found on DOS/WIN systems. The default behavior
+ (with no options) is to extract the archive into the
+ current directory. Use the `-d' option to extract to a
+ directory of your choice.

+comment "Common options for cpio and tar"
+ depends on CPIO || TAR
+
+config FEATURE_UNARCHIVE_TAPE
+ bool "Enable tape drive support"
+ default n
+ depends on CPIO || TAR
+ help
+ I don't think this is needed anymore.
+
+comment "Common options for dpkg and dpkg_deb"
+ depends on DPKG || DPKG_DEB
+
+config FEATURE_DEB_TAR_GZ
+ bool "gzip debian packages (normal)"
+ default y if DPKG || DPKG_DEB
+ depends on DPKG || DPKG_DEB
+ help
+ This is the default compression method inside the debian ar file.
+
+ If you want compatibility with standard .deb's you should say yes here.
+
+config FEATURE_DEB_TAR_BZ2
+ bool "bzip2 debian packages"
+ default n
+ depends on DPKG || DPKG_DEB
+ help
+ This allows dpkg and dpkg-deb to extract deb's that are compressed internally
+ with bzip2 instead of gzip.
+
+ You only want this if you are creating your own custom debian packages that
+ use an internal control.tar.bz2 or data.tar.bz2.
+
+config FEATURE_DEB_TAR_LZMA
+ bool "lzma debian packages"
+ default n
+ depends on DPKG || DPKG_DEB
+ help
+ This allows dpkg and dpkg-deb to extract deb's that are compressed
+ internally with lzma instead of gzip.
+
+ You only want this if you are creating your own custom debian
+ packages that use an internal control.tar.lzma or data.tar.lzma.
