This package provides a complete GCC tool chain for C/C++ development to be installed in user profiles. This includes GCC, as well as libc (headers and binaries, plus debugging symbols in the debug output), and Binutils. GCC is the GNU Compiler Collection.

ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:

• Erasure codes: fast block Reed-Solomon type erasure codes for any encode/decode matrix;

• CRC: fast implementations of cyclic redundancy check. Six different polynomials supported: iscsi32, ieee32, t10dif, ecma64, iso64, jones64;

• Raid: calculate and operate on XOR and P+Q parity found in common RAID implementations;

• Compression: fast deflate-compatible data compression;

• De-compression: fast inflate-compatible data compression;

• igzip: command line application like gzip, accelerated with ISA-L.

QuaZIP is a simple C++ wrapper over Gilles Vollant's ZIP/UNZIP package that can be used to access ZIP archives. It uses Trolltech's Qt toolkit.

QuaZIP allows you to access files inside ZIP archives using QIODevice API, and that means that you can also use QTextStream, QDataStream or whatever you would like to use on your zipped files.

QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both reading from and writing to ZIP archives.

ZZipLib is a library based on zlib for accessing zip files.

LZFSE is a Lempel-Ziv style data compression algorithm using Finite State Entropy coding. It targets similar compression rates at higher compression and decompression speed compared to Deflate using Zlib.

libtar is a C library for manipulating POSIX tar files. It handles adding and extracting files to/from a tar archive.

The purpose of libmspack is to provide both compression and decompression of some loosely related file formats used by Microsoft.

The zchunk compressed file format allows splitting a file into independent chunks. This makes it possible to retrieve only changed chunks when downloading a new version of the file, and also makes zchunk files efficient over rsync. Along with the library, this package provides the following utilities:

unzck

To decompress a zchunk file.

zck

To compress a new zchunk file, or re-compress an existing one.

zck_delta_size

To calculate the difference between two zchunk files.

zck_gen_zdict

To create a dictionary for a zchunk file.

zck_read_header

To read a zchunk header.

zckdl

To download a zchunk file.

unrar-free is a free software version of the non-free unrar utility. This program is a simple command-line front-end to libarchive, and can list and extract not only RAR archives but also other formats supported by libarchive. It does not rival the non-free unrar in terms of features, but special care has been taken to ensure it meets most user's needs.

(N)compress provides the original compress and uncompress programs that used to be the de facto UNIX standard for compressing and uncompressing files. These programs implement a fast, simple Lempel-Ziv (LZW) file compression algorithm.

Lhasa is a replacement for the Unix LHa tool, for decompressing .lzh (LHA / LHarc) and .lzs (LArc) archives. The backend for the tool is a library, so that it can be reused for other purposes. Lhasa aims to be compatible with as many types of .lzh/lzs archives as possible. It also aims to generate the same output as the (non-free) Unix lha tool, so that it will act as a free drop-in replacement.

ZPAQ is a command-line archiver for realistic situations with many duplicate and already compressed files. It backs up only those files modified since the last update. All previous versions remain untouched and can be independently recovered. Identical files are only stored once (known as de-duplication). Archives can also be encrypted.

ZPAQ is intended to back up user data, not entire operating systems. It ignores owner and group IDs, ACLs, extended attributes, or special file types like devices, sockets, or named pipes. It does not follow or restore symbolic links or junctions, and always follows hard links.

Lzop is a file compressor which is very similar to gzip. Lzop uses the LZO data compression library for compression services, and its main advantages over gzip are much higher compression and decompression speed (at the cost of some compression ratio).

GNU Gzip provides data compression and decompression utilities; the typical extension is ".gz". Unlike the "zip" format, it compresses a single file; as a result, it is often used in conjunction with "tar", resulting in ".tar.gz" or ".tgz", etc.

Libdeflate is a library for fast, whole-buffer DEFLATE-based compression and decompression. The supported formats are:

1. DEFLATE (raw)

2. zlib (a.k.a. DEFLATE with a zlib wrapper)

3. gzip (a.k.a. DEFLATE with a gzip wrapper)

Extracts files out of Microsoft Cabinet (.cab) archives

minizip-ng is a zip manipulation library written in C, forked from the zip manipulation library found in the zlib distribution.
