LZ4 is a very fast lossless compression algorithm, providing compression speed
at 400 MB/s per core, scalable with multi-cores CPU. It also features an
extremely fast decoder, with speed in multiple GB/s per core, typically
reaching RAM speed limits on multi-core systems.
A high compression derivative, called LZ4_HC, is also provided. It trades CPU
time for compression ratio.
The libraries are BSD licensed, and the binaries are GPLv2.
The UnRAR library is a minor part of the RAR archiver and contains
RAR uncompression algorithm. UnRAR requires very small volume of
memory to operate.
UnRAR library can be used by other programs to extract RAR archives.
This package contains small fixes from the http://mcmcc.bat.ru/clamav/.

definition as script to automate backup / restore.
The RPM Package Manager is a powerful command line driven package
management system capable of installing, uninstalling, verifying,
querying, and updating computer software packages. Each software
package consists of an archive of files along with information about
the package like its version, a description, and the like. There
is also a related API ("Application Program Interface"), permitting
advanced developers to bypass 'shelling out' to a command line, and
to manage such transactions from within a native coding language.
qpress is a portable file archiver using QuickLZ and designed to utilize fast
storage systems to their max. It's often faster than file copy because the
destination is smaller than the source.
This is a port of a (un)archiver which deals with ACE archives.
This is an extract-only program which allows access to the contents of ARJ
archives. You cannot specify a base directory or select individual files
to extract. UNARJ does not support empty directories or volume labels.
The unRAR utility is a freeware program, distributed with source
code and developed for extracting, testing and viewing the
contents of archives created with the RAR archiver, version 1.50
and above. For the usage and distribution license please read the
file LICENSE.TXT.

Astrometry engine aims to create correct, standards-compliant astrometric
meta data for every useful astronomical image ever taken, past and future,
in any state of archival disarray.
The engine will take any image and return the astrometry world coordinate
system (WCS) -- i.e., a standards-based description of the (usually
nonlinear) transformation between image coordinates and sky coordinates --
with absolutely no "false positives" (but maybe some "no answers"). It
will do its best, even when the input image has no -- or totally incorrect
-- meta-data.
