Elliot Nunn 0ba83392d4 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.

; Change History (most recent first):
;
; <7> 11/21/91 MH Move IMPORT directive out of the SndDispVersion macro
; <6> 11/11/91 MH Remove _MMGetClientIcon. This macro doesn't work because the
; selector nGetClientIcon is not defined. It looks like an
; inadvertant leftover from earlier days. The correct name for the
; macro is _MIDIGetClientIcon, which is already defined later in
; the file, with the selector midiGetClientIcon.
; <5> 6/14/91 JL Checked in official MPW 3.2Ä version. Removed declaration of
; _SoundDispatch as an opword and the conditional.
; <4> 1/30/91 gbm sab, #38: Change the Ôalready including this fileÕ variable to
; all uppercase (for security reasons)
