config BUSYBOX_CONFIG_FEATURE_SEAMLESS_XZ
bool "Make tar, rpm, modprobe etc understand .xz data"
default BUSYBOX_DEFAULT_FEATURE_SEAMLESS_XZ
help
Make tar, rpm, modprobe etc understand .xz data.
config BUSYBOX_CONFIG_FEATURE_SEAMLESS_LZMA
bool "Make tar, rpm, modprobe etc understand .lzma data"
default BUSYBOX_DEFAULT_FEATURE_SEAMLESS_LZMA

Make tar, rpm, modprobe etc understand .bz2 data.
config BUSYBOX_CONFIG_FEATURE_SEAMLESS_GZ
bool "Make tar, rpm, modprobe etc understand .gz data"

help
Make tar, rpm, modprobe etc understand .Z data.
config BUSYBOX_CONFIG_AR
bool "ar"
default BUSYBOX_DEFAULT_AR # needs to be improved to be able to replace binutils ar
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 BUSYBOX_CONFIG_FEATURE_AR_LONG_FILENAMES
bool "Support for 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
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
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 BUSYBOX_CONFIG_BUNZIP2
bool "bunzip2"
default BUSYBOX_DEFAULT_BUNZIP2
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_UNLZMA
bool "unlzma"
default BUSYBOX_DEFAULT_UNLZMA
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 decompression only.
On an x86 system, this applet adds about 4K.
config BUSYBOX_CONFIG_FEATURE_LZMA_FAST
bool "Optimize unlzma for speed"
default BUSYBOX_DEFAULT_FEATURE_LZMA_FAST
depends on BUSYBOX_CONFIG_UNLZMA
help
This option reduces decompression time by about 25% at the cost of
a 1K bigger binary.
config BUSYBOX_CONFIG_LZMA
bool "Provide lzma alias which supports only unpacking"
default BUSYBOX_DEFAULT_LZMA
depends on BUSYBOX_CONFIG_UNLZMA
help
Enable this option if you want commands like "lzma -d" to work.
IOW: you'll get lzma applet, but it will always require -d option.
config BUSYBOX_CONFIG_UNXZ
bool "unxz"
default BUSYBOX_DEFAULT_UNXZ
help
unxz is a unlzma successor.
config BUSYBOX_CONFIG_XZ
bool "Provide xz alias which supports only unpacking"
default BUSYBOX_DEFAULT_XZ
depends on BUSYBOX_CONFIG_UNXZ
help
Enable this option if you want commands like "xz -d" to work.
IOW: you'll get xz applet, but it will always require -d option.
config BUSYBOX_CONFIG_BZIP2
bool "bzip2"
default BUSYBOX_DEFAULT_BZIP2
help
bzip2 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 bzip2, you
should probably say N here.
config BUSYBOX_CONFIG_CPIO
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
"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 BUSYBOX_CONFIG_FEATURE_CPIO_O
bool "Support for archive creation"
default BUSYBOX_DEFAULT_FEATURE_CPIO_O
depends on BUSYBOX_CONFIG_CPIO
help
This implementation of cpio can create cpio archives in the "newc"
format only.
config BUSYBOX_CONFIG_FEATURE_CPIO_P
bool "Support for passthrough mode"
default BUSYBOX_DEFAULT_FEATURE_CPIO_P
depends on BUSYBOX_CONFIG_FEATURE_CPIO_O
help
Passthrough mode. Rarely used.
config BUSYBOX_CONFIG_DPKG
bool "dpkg"
default BUSYBOX_DEFAULT_DPKG
select BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_DPKG_DEB
bool "dpkg_deb"
default BUSYBOX_DEFAULT_DPKG_DEB
select BUSYBOX_CONFIG_FEATURE_SEAMLESS_GZ
help
dpkg-deb 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,
say N here.
config BUSYBOX_CONFIG_FEATURE_DPKG_DEB_EXTRACT_ONLY
bool "Extract only (-x)"
default BUSYBOX_DEFAULT_FEATURE_DPKG_DEB_EXTRACT_ONLY
depends on BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_GZIP
bool "gzip"

help
gzip is used to compress files.
It's probably the most widely used UNIX compression program.

help
Enable big memory options for gzip.
0: small buffers, small hash-tables

bool "lzop compression levels 7,8,9 (not very useful)"
default BUSYBOX_DEFAULT_LZOP_COMPR_HIGH
depends on BUSYBOX_CONFIG_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.

If you enable this option you'll be able to specify
a list of files to include or exclude from an archive.

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.

directory of your choice.
