# PURPOSE:
#	Sets up environment for Intel compilers
# CATEGORY:
#	smei/com/linux
# CALLING SEQUENCE:
#	. $COM/intel_setup
# INPUTS:
#	(none)
# CALLED BY:
#	login
# PROCEDURE:
#	Sets up environment for Intel Fortran and C++ compiler
#	For version 6 and 7 the directory
#	/opt/intel/compiler??/ia32/bin (??=60 or 70)
#	should contain the compilers.
#	For version 8.0 the Fortran and C++ compilers are in
#	separate directories /opt/intel_cc_80 and /opt/intel_fc_80
# MODIFICATION HISTORY:
#	JAN-2003, Paul Hick (UCSD/CASS)
#	MAY-2004, Paul Hick (UCSD/CASS)
#	    Added setup for version 8.0 compilers.
#	    Added check for existence of env var ARCH. If not defined
#	    it is set to $(uname -m)_$(uname -s)
#	MAR-2005, Paul Hick (UCSD/CASS; pphick@ucsd.edu)
#	    Removed support for all version prior to 9.0
