"""MiniAEFrame - A minimal AppleEvent Application framework.

There are two classes:

AEServer -- a mixin class offering nice AE handling.
|
||||
MiniApplication -- a very minimal alternative to FrameWork.py,
|

only suitable for the simplest of AppleEvent servers.

pack(x) converts a Python object to an AEDesc object

unpack(desc) does the reverse

packevent(event, parameters, attributes) sets params and attrs in an AEAppleEvent record

unpackevent(event) returns the parameters and attributes from an AEAppleEvent record

Plus... Lots of classes and routines that help representing AE objects,

x = Character(1, Document("foobar"))
