8.  creation summary:
	cd /fs/cgd/data0/yeager/POP_GRIDS/gx3v5/
	f90 setregionmask.f90
	a.out < setrmask.input

	where
	cat >! setrmask.input << EOF
	100, 116
	horiz_grid_20030806.ieeer8
	topography_20030806.ieeei4
	region.ieeei4
	F
        EOF

	(NOTE: setregionmask.f90 has internal settings for 
	region lat/lon demarcation lines)

	This version is NEW since setregionmask.f90 was
	modified to set the Mediterrean to -7 instead of +7
	as in the previous gx3v5 region mask (region_mask_20030806.ieeei4).
