""" Pyro FLAME: Foreign Location Automatic Module Exposer. Easy but potentially very dangerous way of exposing remote modules and builtins. This is the commandline server. You can start this module as a script from the command line, to easily get a flame server running: :command:`python -m Pyro4.utils.flameserver` or simply: :command:`pyro4-flameserver` You have to explicitly enable Flame first though by setting the FLAME_ENABLED config item.
