Custom Flags

I'm in the process of writing a script where I'd like to have Custom Flags for users on channels. This is a bot where most communication is done on the channels themselves. The users I'd like to have as owners of channels will not be owners in the traditional way where they have access to add more users or alter anyone's flags, but rather have access to more commands than a regular user. To accomplish this I suppose I have to use custom flags, but is there anything I have to manipulate to make the bot recognize these flags?
