open-vcdiff contains an encoder and decoder for the format described in RFC 3284: "The VCDIFF Generic Differencing and Compression Data Format." Given a source file and target file, the encoder produces a compact delta file expressing the differences between the two. The decoder reconstructs the target file from the source and delta files. The package includes libraries, headers, and a command-line executable. The chief reason for developers to use open-vcdiff instead of the existing Xdelta package is that open-vcdiff has been released under the Apache license rather than GPL.

BZip2/OSS-QM is the OSS-QM project's branch of bzip2, which contains a lot of fixes not yet in the original upstream. The primary goal is to provide QM'ed/fixed versions of upstream releases, so they can be built and used without additional patches, especially in sysrooted crosscompiling environments.

Multicrush is a wrapper around pngcrush that distributes the work of brute-force compressing a single image over several pngcrush processes. This gets you a slightly less than a linear speedup, caused by different compression methods having slightly different durations. For example, the author has measured a speedup of 1.92 on a 2-core Intel T5300, and 3.86 on a 4-core Intel Q6600. The only requirements are a copy of pngcrush and at least Python 2.4. If you have version 2.6 or higher, multicrush can automatically detect how many CPUs to use.
