%description
The pyppmd module provides classes and functions for compressing and
decompressing text data, using PPM(Prediction by partial matching)
compression algorithm which has several variations of implementations.
PPMd is the implementation by Dmitry Shkarin. PyPPMD use Igor Pavlov's
range coder introduced in 7-zip.

The API is similar to Python's bz2/lzma/zlib module.

Some parts of th codes are derived from 7-zip, pyzstd and ppmd-cffi.
