Lzip is a lossless data compressor with a user interface similar to the one
of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses
more than bzip2, which makes it well suited for software distribution and
data archiving. Lzip is a clean implementation of the LZMA algorithm.
The lzip file format is designed for long-term data archiving. It is
clean, provides very safe four factor integrity checking, and is backed
by the recovery capabilities of lziprecover.

GNU cpio copies files into or out of a cpio or tar archive. The
archive can be another file on the disk, a magnetic tape, or a pipe.
GNU cpio supports the following archive formats: binary, old ASCII,
new ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1
tar. The tar format is provided for compatibility with the tar
program. By default, cpio creates binary format archives, for
compatibility with older cpio programs. When extracting from
archives, cpio automatically recognizes which kind of archive it
is reading and can read archives created on machines with a different
byte-order.
Note that this port will install these utilities with a 'g' prefix,
e.g. gcpio, but the texinfo documentation will refer to them without
the 'g' prefix.
Gcab is a utility and library mainly made to create Cabinet files, using
GObject/GIO API and provides GIR bindings.
- creation supports plain and basic MSZIP compression
- can open and list files from cabinet, no extraction
The Free Software Foundation's "tar" tape archiver.
GNU tar saves many files together into a single tape or disk archive,
and can restore individual files from the archive. It includes
multivolume support, the ability to archive sparse files, automatic
archive compression/decompression, remote archives and special
features that allow tar to be used for incremental and full backups.
This distribution also includes rmt, the remote tape server.
Note that this port will install these utilities with a 'g' prefix,
e.g. gtar, but the man pages and info documentation will refer to
them without the 'g' prefix.
The rar archiver adds and extracts files to and from an archive. The
archive is usually a regular file, whose ends in the ".rar" suffix.
The archive could be a medium like a floppy diskette, tape or any other
storage device.
Gnome-autoar provides functions, widgets, and gschemas for GNOME applications
which want to use archives as a convient method to tranfer directories over
the internet.
Gzip (GNU zip) is a compression utility designed to be a replacement
for compress. Its main advantages over compress are much better
compression and freedom from patented algorithms.
HA is an archiver which I released in January 1993 as version 0.98.
After that I had plans to improve speed, archive handling etc. which
would have required total rewrite of the code. For that I unfortunately
could not find time. Because there has been quite considerably interest
for internals of HA (especially for the HSC compression method) I
decided to make a source level release from my current test version
(0.999 beta) and place it under GNU General Public License. The sources
for this version are not very consistent or clean, but everything should
work.
There are several improvements which should be made before this could be
called version 1.0. Some of the most obvious of these are:
- Compression methods should be coded in assembler for PC and using more
efficient data structures for 32 bit platforms. Current version does
some things only to overcome 64kB segments of 8086.
- UNIX port has still some problems and is missing some things (for example
a grouping operator in wildcard matches).
- File handling is far from optimum.
- Archive handling is not too clever either.
- Testing should be done more thoroughly as there are many special cases
in compression routines which get used very rarely.
- Documentation of code and algorithms is totally missing.
Gzrecover attempts to skip over bad data in a gzip archive. It will try to to
skip over bad data and extract whatever files might be there.
