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.

Shrinkwrap provides a std::streambuf wrapper for various compression formats, including zstd, xz, gzip, and bgzf.

zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1) and in the GIF image format, the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.

Zutils is a collection of utilities able to process any combination of compressed and uncompressed files transparently. If any given file, including standard input, is compressed, its decompressed content is used instead.

zcat, zcmp, zdiff, and zgrep are improved replacements for the shell scripts provided by GNU gzip. ztest tests the integrity of supported compressed files. zupdate recompresses files with lzip, similar to gzip's znew.

Supported compression formats are bzip2, gzip, lzip, and xz. Zutils uses external compressors: the compressor to be used for each format is configurable at run time, and must be installed separately.

(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.

UCL implements a number of compression algorithms that achieve an excellent compression ratio while allowing fast decompression. Decompression requires no additional memory.

Compared to LZO, the UCL algorithms achieve a better compression ratio but decompression is a little bit slower.

innoextract allows extracting Inno Setup installers under non-Windows systems without running the actual installer using wine.

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

This package provides a parallel implementation of gzip that exploits multiple processors and multiple cores when compressing data.

Squashfs is a highly compressed read-only file system for Linux. It compresses files, inodes, and directories with one of several compressors. All blocks are packed to minimize the data overhead, and block sizes of between 4K and 1M are supported. It is intended to be used for archival use, for live media, and for embedded systems where low overhead is needed.

The squashfs-tools-ng package offers alternative tooling to create and extract such file systems. It is not based on the older squashfs-tools package and its tools have different names:

1. gensquashfs produces SquashFS images from a directory or gen_init_cpio-like file listings and can generate SELinux labels.

2. rdsquashfs inspects and unpacks SquashFS images.

3. sqfs2tar and tar2sqfs convert between SquashFS and tarballs.

4. sqfsdiff compares the contents of two SquashFS images.

These commands are largely command-line wrappers around the included libsquashfs library that intends to make SquashFS available to other applications as an embeddable, extensible archive format.

Both the library and tools operate deterministically: same input will produce byte-for-byte identical output.

Ziptime helps make .zip archives reproducible by replacing timestamps in the file header with a fixed time (1 January 2008).

``Extra fields'' are not changed, so you'll need to use the -X option to zip to prevent it from storing the ``universal time'' field.

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.

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.

Draco is a library for compressing and decompressing 3D geometric meshes and point clouds. It is intended to improve the storage and transmission of 3D graphics.

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

SfArk extractor converts SoundFonts in the compressed legacy sfArk file format to the uncompressed sf2 format.

Zstandard (zstd) is a lossless compression algorithm that combines very fast operation with a compression ratio comparable to that of zlib. In most scenarios, both compression and decompression can be performed in ‘real time’. The compressor can be configured to provide the most suitable trade-off between compression ratio and speed, without affecting decompression speed.
