LZO is a data compression library which is suitable for data de-/compression in real-time. This means it favours speed over compression ratio. LZO implements a number of algorithms with the following features: + Decompression is simple and *very* fast. + Requires no memory for decompression. + Compression is pretty fast. + Requires 64 kB of memory for compression. + Allows you to dial up extra compression at a speed cost in the compressor. The speed of the decompressor is not reduced. + Includes compression levels for generating pre-compressed data which achieve a quite competitive compression ratio. + There is also a compression level which needs only 8 kB for compression. + Algorithm is thread safe. + Algorithm is lossless.

lzop is a file compressor which is very similar to gzip. It uses the LZO library for compression services and its main advantages over gzip are much higher compression and decompression speed (at the cost of some compression ratio). lzop is distributed under the terms of the GNU General Public License (GPL).

A simple binary file format for storing arbitrary meta and user data. A meta archive uses a simple binary file format to store both meta and user data together in a single file. A mar file may be suitable in situations where a full-scale database is not. Both the mar library and the accompanying utility are written in C with the intention of porting to many platforms.

The macutils collection can handle a number of different Macintosh file formats including Binhex, MacBinary, AppleSingle and AppleDouble. There is also support for the Columbia Apple-talk Package. This package contains the following utilities: macunpack hexbin macsave macstream binhex tomac frommac Check out the man pages and /usr/local/share/doc/macutils (or equivalent on your system) for more information.

makeself is a (very small) shell script that makes neat self-extracting shell scripts, and allows you to specify a "setup" command to execute upon finishing. It's sorta like the Windows winzip self-extracting archives.

nomarch extracts files from the old `.arc' archive format. It can also list and test such archives. (nomarch is primarily intended as a `replacement' for the non-Free `arc' program.)

Nulib is a shell-based NuFX archive utility, based loosely on ARC for the IBM PC and ar(1) under Unix. It allows you to perform certain operations on the same archives used by ShrinkIt, e.g. view archive contents, add to archive, extract from archive, and delete from archive. Additionally, it will list and unpack files from Binary II archives.

The Zlib library allows to deflate compressed files and to create gzip (.gz) files. Zlib is free software and small. An archive in ZIP format can contain several files compressed with this method, while a .gz archive can containt only one file. It is a very popular format, that is why I have written a package for reading files compressed within a Zip archive.

NWReckDum is Quake PACK file format (.pak) manipulator. It allows one to list, extract, and create packed game data files easily from command line.

Microsoft "compress.exe/expand.exe" compatible (de)compressor This package contains two programs: msexpand, which decompress files compressed by Microsoft compress.exe utility (e.g. Win 3.x installation files) mscompress, which compress files using LZ77 compression algorithm. Output files can be decompressed using Microsoft expand.exe or msexpand(1).
