+"""A simple example demonstrating how to remove unused commands.
+
+Commands can be removed from  help menu and tab completion by appending their command name to the hidden_commands list.
+These commands will still exist and can be executed and help can be retrieved for them by
+name, they just won't clutter the help menu.
+
+Commands can also be removed entirely by using Python's "del".
