This directory contains routines for a common "procgroup" format for
heterogeneous systems.  The format of this file is:

# comments begin with a pound sign
machine-name [[ex=]name] [[np=]number] [wd=name] [arch=name]

This format was chosen to allow for the simplest specification of a list
of machines that ALSO allows for extensions as needed.  Missing fields
are filled in by the routine.

Additional fields will be added as necessary.  Likely candidates include:
login name
password xxx (!)
various resource limits (nice, cpu, mem, pagefaults)
