Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.
The specification of the Brotli Compressed Data Format is defined in RFC 7932.
Brotli is open-sourced under the MIT License, see the LICENSE file.
Clzip is a lossless data compressor based on the LZMA algorithm, with very safe
integrity checking and a user interface similar to that of gzip or bzip2. Clzip
decompresses almost as fast as gzip and compresses better than bzip2, which
makes it well suited for software distribution and data archiving. Clzip uses
the lzip file format; the files produced by clzip are fully compatible with
lzip-1.4 or newer. Clzip is, in fact, a C language implementation of lzip,
intended for embedded devices or systems lacking a C++ compiler.
Lhasa is a replacement for the Unix LHA tool, for decompressing
".lzh" (LHA/LHarc) and ".lzs" (LArc) archives.
LZ4 is a lossless data compression algorithm that is focused on
compression and decompression speed. It belongs to the LZ77
(Lempel–Ziv) family of byte-oriented compression schemes. It is a
LZP2 fork and provides better compression ratio for text files.
This subpackage provides a GPL command-line utility to make use of
the LZ4 algorithm.
Lzip is a lossless data compressor based on the LZMA algorithm, with very safe integrity checking and a user interface almost identical to the one of bzip2. Lzip is only a data compressor, not an archiver. It has no facilities for multiple files, encryption, or archive-splitting, but, in the Unix tradition, relies instead on separate external utilities such as GNU Tar for these tasks.
Lziprecover is a data recovery tool and decompressor for files in the lzip
compressed data format (.lz) able to repair slightly damaged files, recover
badly damaged files from two or more copies, extract undamaged members from
multi-member files, decompress files and test integrity of files.
Lziprecover is able to recover or decompress files produced by any of the
compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip and pdlzip.
This recovery capability contributes to make the lzip format one of the best
options for long-term data archiving.
Lziprecover is able to efficiently extract a range of bytes from a multi-member
file, because it only decompresses the members containing the desired data.
Lziprecover can print correct total file sizes and ratios even for multi-member
The lzlib compression library provides in-memory LZMA compression and
decompression functions, including integrity checking of the decompressed data.
The compressed data format used by the library is the lzip format.
Plzip is a parallel version of the lzip data compressor. The files
produced by plzip are fully compatible with lzip-1.4 or newer. Plzip
is intended for faster compression/decompression of big files on
Lzip is a lossless data compressor based on the LZMA algorithm, with

of gzip or bzip2. Lzip decompresses almost as fast as gzip and
compresses better than bzip2, which makes it well suited for software
distribution and data archiving.
UPX is a free, portable, extendable, high-performance executable packer
for several different executable formats. It achieves an excellent
compression ratio and offers very fast decompression. Your executables
suffer no memory overhead or other drawbacks.

kmod is a set of tools to handle common tasks with Linux kernel
modules like insert, remove, list, check properties, resolve
dependencies and aliases.
These tools are designed on top of libkmod, a library that is shipped
with kmod. The aim is to be compatible with tools, configurations and
indexes from module-init-tools project.
This utility will dump SPARC OpenPROM device tree in the format similar to Solaris prtconf, that is, in a nicely readable compact format.
SILO, the Sparc Improved boot LOader, is a booting loader program
that runs from the PROM of SPARC (32-bit) and UltraSPARC (64-bit)
This package contains a large variety of low-level system utilities that are necessary for a Linux system to function. It contains the mount program, the fdisk configuration tool, and more.
If your library is a basic building block (-> subject to interpretation) and topically does not fit into another project, this may be the place for it.
1. We only build against the standard repositories for the distros
2. Users only get access to their packages. We should keep the number of project maintainers as small as possible
