-  # Gateway id conversion forms a gateway between different DRb protocols or
-  # networks.
-  #
-  # The gateway needs to install this id conversion and create servers for
-  # each of the protocols or networks it will be a gateway between.  It then
-  # needs to create a server that attaches to each of these networks.  For
-  # example:
-  #
-  #   require 'drb/drb'
-  #   require 'drb/unix'
-  #   require 'drb/gw'
-  #
-  #   DRb.install_id_conv DRb::GWIdConv.new
-  #   gw = DRb::GW.new
-  #   s1 = DRb::DRbServer.new 'drbunix:/path/to/gateway', gw
-  #   s2 = DRb::DRbServer.new 'druby://example:10000', gw
-  #
-  #   s1.thread.join
-  #   s2.thread.join
-  #
-  # Each client must register services with the gateway, for example:
-  #
-  #   DRb.start_service 'drbunix:', nil # an anonymous server
-  #   gw = DRbObject.new nil, 'drbunix:/path/to/gateway'
-  #   gw[:unix] = some_service
-  #   DRb.thread.join
