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.

Change History (most recent first):
<13> 8/26/92 DTY Roll in latest changes for A/UX.
<12> 1/22/92 DTY Take the synFOND field out of the synthetic strike table
structure. WeÕre gauranteeing unique font IDs, so this extra
differentiation wonÕt be necessary.
<11> 11/15/91 DTY Added synFOND to the SynEntry structure. (We might need to
store this information elsewhere if it turns out that developers
are looking at the synthetic fonts.
<10> 9/16/91 DFH Added GetCPUStatusRegister and SR definitions.
<9> 4/1/91 DFH (with John Iarocci) Merge in latest AUX support code. NOTE: No
AUX support code is referenced unless the build defines the
HAS_AUX_PROCESSMGR condition.
<8> 3/1/91 DFH KST,WS#DFH-910301a: Added xfiScriptCodeMask.
<7> 1/21/91 DFH (KSM) Removed system menu IDs, since they are now in
MenuMgrPriv.a.
<6> 1/15/91 DFH (VL) Conditionalize out the AUX call macros.
<4> 12/10/90 DFH Moved file attribute and finder flag equates from
OSDispatchPrivate.h.
<3> 12/5/90 DFH Added #defines for prettier calls to AuxDispatch. Removed
NewFXInfo since FXInfo is now in Files.h.
<0> 10/25/86 PYG New Today.
