Resending this after getting an error that I sent this twice although I
didn't send it twice... Strange...

I just downloaded wgrib2 from NCEP. There is no -small option.
Is it -ijsmall_grib or -small_grib?

Currently, there is a rendering in progress. I'll upload the changes
after the current rotation is finished and let it run with the 2300UTC
rotation as a test.

About the control file... I anyway call g2ctl after wgrib2, so that
shouldn't be a problem, right?

Terve,
Stefan
