			# this script modifies the OpenMP directives in LAMMPS
			# in a way, so that they are also accepted by the PGI
			# compilers. This modification incurs a performance
			# penalty, though, so it is not part of the regular code.
			#
			# to apply the hack. go to src/, install all packages
			# as needed and then run: sh ../tools/hack_openmp_for_pgi.sh
			# this needs to be repeated after each "make package-update"
