[gradsusr] Wgrib2 / g2ctl / gribmap

[Andrew Revering]

I'm using version 0.0.8.4 of g2ctl and 0.1.9.1 of wgrib2, and gribmap for
grads 2.0.1.oga.1
An example grib2 file I'm having trouble with can be downloaded here:
http://www.f5maps.com/ruc.grib

... which is a renamed copy of the NCEP server file for the RUC model found
at:
ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/ruc/prod

naming convention: ruc2.tccz.pgrb20xxx.grib2
AWIPS - Regional - CONUS  (Lambert Conformal)(20-km Resolution)
