Hello all,
This patch adds more "Help" text to the config system. Almost
all applets now have a help entry. Also, I cleaned up the spacing of
the existing text so that things are consistent. This patch is against
this morning's CVS.

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.

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.

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.

This reduced dpkg-deb to the equivalent of "ar -p <deb> data.tar.gz | tar -zx".

This allows dpkg and dpkg-deb to extract deb's that are compressed internally
