evennia/evennia/game_template/commands

commands/

This folder holds modules for implementing one's own commands and command sets. All the modules' classes are essentially empty and just imports the default implementations from Evennia; so adding anything to them will start overloading the defaults.

You can change the organisation of this directory as you see fit, just remember that if you change any of the default command set classes' locations, you need to add the appropriate paths to server/conf/settings.py so that Evennia knows where to find them. Also remember that if you create new sub directories you must put (optionally empty) __init__.py files in there so that Python can find your modules.
