     description = """
     Defines an intbitset data object to hold unordered sets of
     unsigned integers with ultra fast set operations, implemented via
     bit vectors and Python C extension to optimize speed and memory
     usage.
 
     Emulates the Python built-in set class interface with some
     additional specific methods such as its own fast dump and load
     marshalling functions.  Uses real bits to optimize memory usage,
     so may have issues with endianness if you transport serialized
     bitsets between various machine architectures.
