    (description
     "Python is a remarkably powerful dynamic programming language that
is used in a wide variety of application domains.  Some of its key
distinguishing features include: clear, readable syntax; strong
introspection capabilities; intuitive object orientation; natural
expression of procedural code; full modularity, supporting hierarchical
packages; exception-based error handling; and very high level dynamic
data types.")
