help
ar is an archival utility program used to create, modify, and
extract contents from archives. In practice, it is used exclusively
for object module archives used by compilers.
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: most compilers come with their own ar utility.
config BUSYBOX_CONFIG_FEATURE_AR_LONG_FILENAMES
bool "Support long filenames (not needed for debs)"
default BUSYBOX_DEFAULT_FEATURE_AR_LONG_FILENAMES
depends on BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_AR_CREATE
bool "Support archive creation"
default BUSYBOX_DEFAULT_FEATURE_AR_CREATE
depends on BUSYBOX_CONFIG_AR
help
This enables archive creation (-c and -r) with busybox ar.
config BUSYBOX_CONFIG_UNCOMPRESS
bool "uncompress"
default BUSYBOX_DEFAULT_UNCOMPRESS # ancient
help
uncompress is used to decompress archives created by compress.
Not much used anymore, replaced by gzip/gunzip.
config BUSYBOX_CONFIG_GUNZIP
bool "gunzip"
default BUSYBOX_DEFAULT_GUNZIP
select BUSYBOX_CONFIG_FEATURE_GZIP_DECOMPRESS
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.

default BUSYBOX_DEFAULT_BUNZIP2
select BUSYBOX_CONFIG_FEATURE_BZIP2_DECOMPRESS
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.
config BUSYBOX_CONFIG_BZCAT

This option reduces decompression time by about 25% at the cost of
a 1K bigger binary.

bool "cpio"
default BUSYBOX_DEFAULT_CPIO
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
