Readme.Windows I (WNE) do not run grib2ctl.pl under windows. Trying to support grib2ctl under windows was difficult. Couldn't answer questions and never knew if code changes broke the script. Did a significant code change and with no feedback from windows users for several months, I can no longer determine whether the code works under windows. I have decided to give up the pretense of supporting grib2ctl under windows. New Policy Grib2ctl.pl may or may not work under windows. If it does, good for you. If it doesn't, well you can either fix it, run linux or do without. Grib2ctl.pl.windows probably will work under windows but that is not a given. If you want to submit bug fixes to make the program windows compatible, fine. I will add them to the official source code. However, YMMV under windows.
