+genomic interval dataframes in Python.  Bioframe enables access to a rich set
+of dataframe operations.  Working in Python enables rapid visualization and
+iteration of genomic analyses.  The philosophy underlying bioframe is to
+enable flexible operations.  Instead of creating a function for every possible
+use-case, we encourage users to compose functions to achieve their goals.")
