  • Revision ID: teddy@fukt.bsnet.se-20080721015031-ivjiclli2j06hwgs
* Makefile: Include targets for all binaries.

* plugins.d/Makefile: Do nothing but call the parent Makefile.

* server.py: Added copyright statement and information.
  (Client.__init__): Added doc string.
  (Client.stop): Bug fix: Only log message if stopping for the first
                 time.  Check if the "stop_initiator_tag" and
                 "checker_initiator_tag" attributes exist before using
                 them.
  (Client.__del__): Call self.stop() instead of doing things here.
  (Client.checker_callback): Set self.checker_callback_tag and
                             self.checker to None unconditionally and
                             immediately.
  (Client.stop_checker): Added some checks to handle multiple calls.
  (tcp_handler.handle): Use "self.server.clients" instead of "clients".
  (__main__): Moved all code to the "main" function.
  (main): New.  New option "--address".  Instantiate IPv6_TCPServer
          with "options.address".  Log before starting main loop.
  (main.cleanup) Use "clients.pop()" to remove clients from the set as
                 they are stopped.
