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):
<SM28> 7/21/93 joe Back out <SM27>.
<27> 10/28/92 DTY Use new Get/Set macros to access ExpandMem.
<26> 9/25/92 DRF Get rid of MyGestalt, since inline glue exists
<25> 8/26/92 DTY Change ModSquadÕs funky conditional to use #ifdefs like everyone
else.
<24> 8/26/92 DTY Roll in latest changes for A/UX.
<23> 8/17/92 hjcr Adding support for OCE's "defer drag" feature. Conditionally
compiled under MODSQUAD
<22> 5/11/92 JSM #1029437 <DC>: Set emProcessMgrExists to true after calling
MyNewGestalt().
<21> 3/30/92 DTY #1025416,<DDG>: Look for Skia in InitConfig and set skiaExists
accordingly.
<20> 3/23/92 JSM OSEvents.h is obsolete, use Events.h.
<19> 1/11/92 YK Initialize new globals for the TSM.
<18> 11/22/91 DTY Initialize allocateGMBlkInSysHeap to be false. GMBlk normally
tries to allocate itÕs block in the Process Manager zone first,
except when an 'obit' event is being sent.
<17> 11/1/91 DTY Set TOPMAPHANDLE to point to the first system override map
instead of SYSMAPHANDLE in main().
<16> 10/15/91 YK Added initializing code for the Text Service Manager.
<15> 9/16/91 DFH Set initialProcessSR in InitializeScheduler. Needed for
NuKernel.
<14> 5/23/91 dba do a style of coercion that MPW 3.2 C likes
<13> 1/28/91 DFH JSM,#81425: Removed inhibit_DAs mechanism.
<12> 1/15/91 DFH (VL) Conditionalize out FloatAUXUp.
<11> 1/14/91 DFH (dba) Make system mode per process.
<10> 1/14/91 DFH (JDR) Conditionalize out AUX support.
<8> 1/8/91 DFH (rdd) Got rid of pErrantProcess since it is no longer needed.
<7> 12/15/90 DFH Main now initializes srcMyScrapInfo.pScrapOwner.
<6> 12/14/90 DFH InitializeScheduler now initializes kernelMode.
<5> 12/13/90 JWM For 7.0B3, sending the AppleEvent message to the network
extension (Network Setup) in the shell program (Finder 7.0)
about the PPCToolbox not initializing was removed.
<4> 12/5/90 DFH Integrated AUX support.
<3> 11/26/90 DFH Change trespass() to dbmsg().
<0> 9/2/86 ELR New Today.
