    """Provides a framework to perform Non-negative Matrix Factorization (NMF).
    The package implements a set of already published algorithms and seeding
    methods, and provides a framework to test, develop and plug new/custom
    algorithms. Most of the built-in algorithms have been optimized in C++, and
    the main interface function provides an easy way of performing parallel
    computations on multicore machines.."""
