Elliot Nunn 4325cdcc78 Bring in CubeE sources
Resource forks are included only for .rsrc files. These are DeRezzed into their data fork. 'ckid' resources, from the Projector VCS, are not included.

The Tools directory, containing mostly junk, is also excluded.

File: AppleEventExtensions.h
Contains: Interfaces to routines in AppleEventExtensions.c. Also contains some
AppleEvent Transport Format (AETF) information that we would ideally
not know about. Unfortunately, the AppleEvent Manager was not ready
to use when we needed to write these routines. By agreement between
the AppleEvent Manager authors and the System 7.0 decision makers,
the initial AETF was solidified enough for Finder and the Process Mgr
to use. This AETF format is to be acceptable in all future revisions
of the AppleEvent Manager.
