This command specifies which bot will manage the room. It must be set before any of the other settings will take effect since the bot manages the room and enforces the settings.
/as chan #conferenceroom set bot SupportBot
A single bot can manage several rooms. You might want to use multiple bots if you want to manage a very large number of rooms using server bots and to give different people access to several but not all of the rooms. Then you can group the rooms based on which people may have access to which and give out the bot's password to them. This would minimize the number of passwords people need to remember. Since anyone with the bot's password can be opped in all the rooms the bot manages, you'd want to be sure that the rooms it is in are all intended to give ops to the same people.
