[gradsusr] Is it necessary to install perl to Read Grib2 with GrADS?

[Jennifer Adams]

Have a look at http://iges.org/grads/gadoc/grib.html -- this doc page  
gives pretty explicit instructions for how to handle grib and grib2  
data with GrADS. The gribmap utility (which is part of the GrADS  
distribution) handles grib and grib2 files. The g2ctl program is  
extremely handy, but not strictly required for creating a descriptor  
file. Perl will probably work out of your home directory, but be sure  
to change the path in the first line of the g2ctl code to point to  
your custom location.
