- '''Tools for use in AppleEvent clients and 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,
- ranges, conditionals, logicals, etc., so you can write, e.g.:
-
- x = Character(1, Document("foobar"))
-
- and pack(x) will create an AE object reference equivalent to AppleScript\'s
-
- character 1 of document "foobar"
-
- Some of the stuff that appears to be exported from this module comes from other
- files: the pack stuff from aepack, the objects from aetypes.
