I implemented my extension like:

module Avalon
     class ShellInterface < Roby::Interface::CommandLibrary

         def set_state(state, substate)
             State.lowlevel_state = state
             State.lowlevel_substate = substate
         end
         command :set_state, "set the current runstate for Avalon as 
state,substate pair",
             :state => "The given State (0=> off, 3=> autonomous)",
             :substate => "The given substate"

         def tester
             STDOUT.puts "hallo test funktion"
         end
         command :tester, "This tests this module"
     end
end
module Robot
     def self.avalon
         STDOUT.puts "Loading the new avalon interface"
         @avalon_interface_internal ||= Avalon::ShellInterface.new(Roby.app)
     end
end

Roby::Interface::Interface.subcommand 'avalon', Avalon::ShellInterface, 
'Commands specific to Avalon'

Unfortunatly it seems it does not get loaded.

localhost:48902 > avalon.class
=> NilClass
