+%description
+
+The argparse module is an optparse-inspired command line parser that
+improves on optparse by:
+ * handling both optional and positional arguments
+ * supporting parsers that dispatch to sub-parsers
+ * producing more informative usage messages
+ * supporting actions that consume any number of command-line args
+ * allowing types and actions to be specified with simple callables 
+    instead of hacking class attributes like STORE_ACTIONS or CHECK_METHODS 
+
+as well as including a number of other more minor improvements on the
+optparse API.
