+``cmd2`` is an extension of cmd_, the Python Standard Library's module for
+creating simple interactive command-line applications.
+
+``cmd2`` can be used as a drop-in replacement for cmd_. Simply importing ``cmd2``
+in place of cmd_ will add many features to an application without any further
+modifications.
