Elliot Nunn 5b0f0cc134 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.

This file is used in these builds: BigBang
Change History (most recent first):
<SM2> 8/26/93 IH Added types for fixed and rect (used by Display Manager events).
<18> 7/30/91 JL Updated Copyright.
<17> 6/14/91 JL Checked in official MPW 3.2Ä version. Lined up parameter lists
vertically to match pascal file. Adjusted comment formats to
match Pascal file. Temporarily lost updated copyright date but
this will be resolved later.
<16> 2/5/91 stb eeh: add const ÉÊ* for non-VAR record parameters
<15> 2/1/91 DFH stb,WS#DFH-910131c:Moved and renamed Process Mgr defined
AppleEvent codes to this file. Put old names in
AppleEventsInternal.h since we don't want to break any compiles
at this point.
<14> 1/30/91 JL Changed #defines to enums
<13> 1/25/91 stb JDR: harmonize with AppleEvents.p
<12> 10/2/90 Lai Matches AppleEvents.p.
<11> DFH 16 Apr 90 Changed saeOpenDocumentMsgID to 'odoc', saePrintDocumentMsgID
to 'pdoc'. Added saeLaunchedWithoutDocs, saeAnswer,
aeErrorValueKeyword, and AppleEventReply.
<10> ngk 4/2/90 Renamed class field in HighLevelEventRecord
<9> DFH 23 Mar 90 Corrected the majorVersion to be a short, as per ERS.
<8> ngk 3/22/90 Changed AETFDescriptor AETFParameter in regular expr.
<7> ngk 3/20/90 Change to new 7.0a8 format for message buffers. Removed
constants and structs for non-standard appleevents
<6> DFH 12 Mar 90 Added AppleEventMessage
<5> DFH 12 Mar 90 Removed aeDebuggerNotify
1.1 ngk 12/01/1989 Renamed aeUnexpectedQuit to aeApplicationDied, and
refcon to amsRefCon
1.0 ngk 11/01/1989 initial EASE release
To Do:
