User's Guide on EPICS build system

[Claude Saunders <saunders@aps.anl.gov>]

I would like to STRONGLY encourage that a separate guide to
the epics/config build system be created. This is a very
capable, easily customized build system. Yet people
are continually developing and using their own. Or, alternately,
the multitude of variables are misused because their purpose is 
a mystery. All because it is basically completely undocumented.
If I had a nickel for every time I was asked where the
doc for it is...

I think embedding the doc for this in some other epics manual is
not a good idea. The build system is an extremely useful
product in and of itself. I take it with me wherever I go.
I think it should be actively documented and advertised.
