bzlib Hackage

Compression and decompression in the bzip2 format

This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the bz2 C library so it has high performance.

It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full bzip2 feature set.
