# lzma-cf

A Python LZMA & XZ library with greater control over compression parameters.

In addition to CPython's stdlib [`lzma`][CPython-lzma], lzma-cf can

- Compress and decompress XZ files in multithreaded mode

## History

lzma-cf is derived from code that has passed through multiple projects by
multiple authors

1. [CPython] 3.3.0 added `lzma` to the stdlib in `_lzmamodule.c` & `lzma.py`
1. [backports.lzma] repackaged CPython C-API code & adapted it
1. [lzmaffi] forked backports.lzma & changed C-API bindings to [CFFI] bindings
1. [PyPy] incorporated lzmaffi code into their stdlib & updated it
1. lzma-cf (this project) uses PyPy code and builds on it
