            This package contains the utilities for constructing and manipulating
            `twoBit files <https://genome.ucsc.edu/goldenpath/help/twoBit.html>`_.
            The utilities were created by the
            `Genome Bioinformatics Group <https://genome.ucsc.edu/staff.html>`_
            at the UCSC Genomics Institute.

            The twoBit file format is designed to store genomic sequences and the
            associated repeat masking information. The twoBit file is used by the
            UCSC Genome Browser and by tools such as
            `BLAT <https://genome.ucsc.edu/goldenpath/help/blatSpec.html>`_.
