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.

; Contains: Code to do smarter loading of Process Manager segments to reduce
; system heap fragmentation. Based on GregÕs 7 Up code.

load 'StandardEqu.d'
include 'LinkedPatchMacros.a'
; Loading these segments lower in the system heap helps reduce fragmentation of the
; system heap. Preloading resources from the System file doesnÕt work because they
; come in before the decompression hooks are installed. For each Process Manager
; segment in our list, find out itÕs size, reserve enough space for it, and load
; it low in the heap.
