Fivebit is a Python 3 compression library for short text strings. It compresses short strings of text into five bit encoding, which yields a 37.5% reduction for lowercase ASCII. There is also a dictionary for the 1024 most common English words (3 letters or longer). Punctuation, digits, and normal symbols will usually take up 10 bits each, and oddball Unicode characters will take up more space again.

LZHAM is a general purpose lossless data compression library that borrows many ideas from LZMA, but purposely makes several key tradeoffs that favor decompression speed over compression ratio. LZHAM's compression ratio is typically within .5% of LZMA, but decompresses 2-3 times faster. LZHAM's compressor is heavily threaded in a way that does not sacrifice compression ratio. The decompressor supports streaming and memory to memory decompression, and is designed to be particularly fast on embedded devices, handhelds, and game console platforms.

fistgen is the FiST language code generator, used to create stackable file systems out of templates and a high-level language. This package comes with stackable file system templates for Linux, Solaris, and FreeBSD. It also contains several sample file systems built using the FiST language: an encryption file system, a compression file system, and more - all of which are written as portable stackable file systems.

rewrite reads a file, feeding its content through a shell command or a pipeline, and writes it back to the file. It allows for in place (re)compression, for example. For large multi-part archives, you may not otherwise be able to uncompress and recompress the data again because of lack of temporary disk space. If the output from the pipeline is bigger than the file, the program will continue to allocate memory to buffer the difference, and it will never overwrite data in the file before reading it.
