+  BotModule is the base class for the modules that enhance the rbot
+  functionality. Rather than subclassing BotModule, however, one should
+  subclass either CoreBotModule (reserved for system modules) or Plugin
+  (for user plugins).
+
+  A BotModule interacts with Irc events by defining one or more of the following
+  methods, which get called as appropriate when the corresponding Irc event
