 1  """ 
 2  interfaces are where the comunication to the internet happends 
 3   
 4  Interfaces communicate with L{modules<module>} through L{events}. modules 
 5  will do the functionallity of the bot, using interfaces for communicate with 
 6  mailing lists, irc, ... 
 7   
 8  Interface inheritate from L{complement} from where you can 
 9  L{log<emma.complement.Complement.log>}, L{use locks<emma.complement.use_lock>}, 
10  ... Everything in an interface happens in parallel on several threads, so for 
11  class variables L{locks<emma.complement.use_lock>} should be use.
