python3-pyppmd: python3-pyppmd (PPMd compression/decompression library) python3-pyppmd: python3-pyppmd: pyppmd module provides classes and functions for compressing and python3-pyppmd: decompressing text data, using PPM(Prediction by partial matching) python3-pyppmd: compression algorithm which has several variations of python3-pyppmd: implementations. PPMd is the implementation by Dmitry Shkarin. python3-pyppmd: PyPPMD use Igor Pavlov's range coder introduced in 7-zip. python3-pyppmd: python3-pyppmd: python3-pyppmd: python3-pyppmd:
