grib2ctl.pl problem

[Michael E Masscotte]

Wesley,

I would like to second the request for adding minutes to g2ctl. We run
models in house with output every 15 minutes. We handle it now with some
scripts to modify the ctl file, but it would be really nice to have
g2ctl handle it internally.

Thanks,
-Mike
