verf:
  use forecast verification time

   grib2ctl.pl -verf IN.grb >IN.ctl
   gribmap -i IN.ctl

no verf:
  use analysis or start of fcst time

     grib2ctl.pl IN.grb >IN.ctl
     gribmap -0 -i IN.ctl

-b:
  use forecast verf time or start of fcst interval

   grib2ctl.pl -b IN.grb >IN.ctl
   gribmap -b -i IN.ctl




-ec_gbl:  This is an old old option and I had forgotten what
it does.  Thinned grids come in two flavors, regional
and global.  Grib1 only defined one flavor.  When the
ECMWF introduced a global thinned grid and I added an option to handle it.
