      """BEAST is a cross-platform program for Bayesian inference using MCMC
         of molecular sequences. It is entirely orientated towards rooted,
         time-measured phylogenies inferred using strict or relaxed molecular
         clock models. It can be used as a method of reconstructing phylogenies
         but is also a framework for testing evolutionary hypotheses without
         conditioning on a single tree topology."""
