The hpack Multi-System Archiver is an archiver that was written to allow the transfer of archived data to differ- ent systems. In the past archivers have traditionally been available for single systems only, for example PKZIP and LHARC for the IBM PC, Larc for the Amiga, StuffIt and Compactor for the Macintosh, and tar and compress for UNIX systems (while these archivers are available on other systems, their use is not widespread). Open-keys security included.

LCAB is a small program that creates a Microsoft Cabinet (.CAB) file from a set of input files.

The XAR project aims to provide an easily extensible archive format. Important design decisions include an easily extensible XML table of contents for random access to archived files, storing the toc at the beginning of the archive to allow for efficient handling of streamed archives, the ability to handle files of arbitrarily large sizes, the ability to choose independent encodings for individual files in the archive, the ability to store checksums for individual files in both compressed and uncompressed form, and the ability to query the table of content's rich meta-data.

A tiny C library and sample program to extract data compressed using dozen popular archivers. Currently following formats are supported: - tar (*.tar) - tar + gzip'ed (*.tar.gz, *.tgz) (deflate) - zip (*.zip) (implode, deflate) - lzh (*.lzh) (lh0, lh1, lh2, lh3, lh4, lh5, lh6, lzs, lz5, lz4) - MIME multipart

The libcomprex library transparently handles automatic compression and decompression of files. The API is similar to C's built-in file access functions, which provides a smooth transition to libcomprex. libcomprex can also open uncompressed files, making it a good replacement for the native file access functions.

Dynamite is a tool and library for decompressing data compressed with the PKWARE Data Compression Library.

This is a simple command line implementation of the LZMA compression algorithm from the LZMA SDK. It uses a raw LZMA format instead of the xz or 7z container formats, and produces compression ratios that are usually about 25-30% better than bzip2, and decompression speeds that are about twice as fast. The disadvantages are higher CPU and RAM requirements for compression.

This package includes a thin wrapper library of LZMA SDK.

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.

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.
