Fast, simple object-to-object and broadcast signaling

Blinker provides a fast dispatching system that allows any number of
interested parties to subscribe to events, or "signals".

Signal receivers can subscribe to specific senders or receive signals
sent by any sender.
>>> from blinker import signal
>>> started = signal('round-started')
>>> def each(round):
...     print "Round %s!" % round
...
>>> started.connect(each)
>>> def round_two(round):
...     print "This is round two."
...
>>> started.connect(round_two, sender=2)
>>> for round in range(1, 4):
...     started.send(round)
...
Round 1!
Round 2!
This is round two.
Round 3!
Requirements

Blinker requires Python 2.4 or higher, Python 3.0 or higher, or Jython 2.5 or higher.
