evennia/game/gamesrc/commands/empty_cmdset.py

"""
This is the second component of using a Command in your game - a
command set.  A cmdset groups any number of commands together. CmdSets
are stored on character and objects and all available cmdsets are
searched when Evennia tries to determine if a command is
available. Sets can be merged and combined in many different ways (see
the docs).

You can use the classes below as templates for extending the game with
new command sets; you can also import the default Evennia cmdset and
extend/overload that.

To change default cmdset (the one all character start the game with), 
Create your custom commands in other modules 
(inheriting from game.gamesrc.commands.basecommand), add them to a 
cmdset class, then set your settings.CMDSET_DEFAULT to point to this
new cmdset class.
