Subj: 	tricky way to point to local sandbox tools - comments?

What do you think of this?  I was just helping someone from Joe Mario's
group who wanted to isolate his platinum sandbox and have local tools,
sources, etc., and I came up with this... 

This simple, elegant, solution will redefine COMP_HOST_ROOT and all
derived variables, as well as redefining SOURCEDIR to "" so that 'make'
wil only be able to reference files local to the sandbox:

In your sandbox, create the following 2 line file; that's it!

    ::::::::::::::
    rc_files/custom
    ::::::::::::::
    include ./local
    include ../link/rc_files/custom.build

To completely be isolated, do this to make your rc_files' includes all local
(assumes you're backed to a fully populated tree like .nightly or a .bl):

	mv link link.ln
        mkdir link
        cp -r link.ln/rc_files link
        cp -r link.ln/link link
