+     "The fastbencode Python package implements the bencode serialization
+format for storing and transmitting loosely structured data, originally used
+by BitTorrent.
+
+The format can encode four different types of values: byte strings, integers,
+lists, and dictionaries (associative arrays).  It's simple and unaffected by
+endianness,
+
+This package includes both a pure-Python version and an optional C extension
+based on Cython.  Both provide the same functionality, but the C version has
+significantly better performance.")
