menu "Archival Utilities"
config 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 XXX bytes.
Unless you have a specific application which requires ar, you should
probably say N here.
config CONFIG_FEATURE_AR_LONG_FILENAMES
bool " Enable support for long filenames (not need for debs)"
default n
depends on 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 CONFIG_BUNZIP2
bool "bunzip2"
default n
help
bunzip2 is an 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 XXX bytes.
Unless you have a specific application which requires bunzip2, you
should probably say N here.
config 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 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 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 CONFIG_FEATURE_DPKG_DEB_EXTRACT_ONLY
bool " extract only (-x)"
default n
depends on CONFIG_DPKG_DEB
help
This reduced 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 CONFIG_FEATURE_DEB_TAR_GZ
bool " gzip debian packages (normal)"
default y if CONFIG_DPKG || CONFIG_DPKG_DEB
depends on CONFIG_DPKG || CONFIG_DPKG_DEB
help
This is the default compression method inside the debian ar file.
If you want compatability with standard .deb's you should say yes here.
config CONFIG_FEATURE_DEB_TAR_BZ2
bool " bzip2 debian packages"
default n
depends on CONFIG_DPKG || CONFIG_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 is your are creating your own custom debian packages that
use an internal control.tar.bz2 or data.tar.bz2.
config CONFIG_GUNZIP
bool "gunzip"
default n

config CONFIG_FEATURE_GUNZIP_UNCOMPRESS
