    """HAL is a structure to efficiently store and index multiple
    genome alignments and ancestral reconstructions.

    HAL is a graph-based representation which provides several advantages
    over matrix/block-based formats such as MAF, such as
    improved scalability and the ability to perform queries with
    respect to an arbitrary reference or subtree."""
