    """Computes 46 optimized distance and similarity measures for comparing
    probability functions (Drost (2018) <doi:10.21105/joss.00765>). These
    comparisons between probability functions have their foundations in a broad
    range of scientific disciplines from mathematics to ecology. The aim of
    this package is to provide a core framework for clustering, classification,
    statistical inference, goodness-of-fit, non-parametric statistics,
    information theory, and machine learning tasks that are based on comparing
    univariate or multivariate probability functions."""
