Should play around with it if you got some time, can make using them not only easier, but more effective.
It uses the LUA langauge for commands, information on which can be found here:

And is rather simple to use/edit, although you should stay away from making bots. that takes all the fun/challenge out of the game.
Sample AI that im using/editing/learning from can be found here:

Stick the files from the zip into your qrRO folder in AI>USER_AI, when moving files click yes to replace, it has built in standard AI files too.
Don't forget to back the AI folder up just incase you mess something up, and playing around with it is pretty straightfoward, when editing it choose notepad or an appropriate program for text editing.
and easy enough once all the files are in, get in-game and type /hoai to change to the custom scripts, relog and its all set. (future changes to homunc ai require a re-summon, while user commands require a relog)
