8.  creation summary:
	Created a 60-level kmt for the x3 horizontal mesh from 2-minute
	etopo bathymetry data (/cgd/oce/yeager/obs/topo/etopo_merge_bedmap.readme)
	using /fis01/cgd/home/yeager/gen_POPinput/gen_POPbathymetry.F90
	with the following inputs (gen_POPbathymetry.nml):
	&in_parm
	  nlng = 100
	  nlat = 116
	  hmin = 5.
	  nsmooth = 1
	  landfrac = 0.75
	  genkmt = 1
	  km = 60
	  kmtmin = 3
	  POP_horz_grid = 'horiz_grid_20030806.ieeer8'
	  POP_vert_grid = 'gx1v6_vert_grid'
	  POP_bath_file = 'gx3v7_bathym.ieeer8'
	  POP_kmt_file = 'gx3v7_kmt.ieeei4'
	  POP_lmask_file = 'gx3v7_lmask.ieeei4'
	  nx_o = 10800
	  ny_o = 5400
	  OBS_bath = '/cgd/oce/yeager/obs/topo/etopo_merge_bedmap.da'
	/

	Then, merged the resulting kmt (gx3v7_kmt.ieeei4) with the landmask
	used in gx3v5 using
	/gpfs/fis01/cgd/oce/yeager/POP_grids/gx3v7/merge_gx3v5_gx3v7.ncl
        This generated the kmt file: topography_20090812.ieeei4

 	Then, finalized the kmt for overflows according to Briegleb's
	hand modifications using
	/gpfs/fis01/cgd/oce/yeager/POP_grids/gx3v7/kmt_overflow_mods.run
    	This generated the kmt file: topography_20090828.ieeei4
