New in version 2.3.
This module provides a comprehensive interface for the bz2 compression library.
It implements a complete file interface, one-shot (de)compression functions,
and types for sequential (de)compression.
Here is a resume of the features offered by the bz2 module:

      readline(), readlines(),
      writelines(), seek(), etc;
- BZ2File class implements emulated seek() support;

- BZ2File class offers an optimized line iteration using
      the readahead algorithm borrowed from file objects;

      BZ2Decompressor classes;
- One-shot (de)compression supported by compress() and
      decompress() functions;
