This module brings Django Signals into Evennia. These are events that can be subscribed to by importing a given Signal and using the following code.

THIS_SIGNAL.connect(callback, sender_object)

When other code calls THIS_SIGNAL.send(sender, **kwargs), the callback will be triggered.

Callbacks must be on the following format:

def my_callback(sender, **kwargs):
    # ...

This is used on top of hooks to make certain features easier to add to contribs without necessitating a full takeover of hooks that may be in high demand.
