[ncl-talk] Grib file warning

[Dennis Shea]

Dave Brown is the person. He is off today.

See the '*File I/O improvements'* of the most recent version (6.3.0)
   http://www.ncl.ucar.edu/current_release.shtml

The GRIB stuff is a moving target.  No surprise that no commercial tools
would support it.

What machine are upu working on?
