Dear All,
Many thanks to John Huddleston and Don Hooper who have provided more
pre-compiled binary distributions of GrADS-2.0.a3. Now we have MS
Windows (requires cygwin) and 32-bit linux (i686) and SunOS. The
downloads page (http://iges.org/grads/downloads.html) has been
updated. If you scroll down to the "Supplementary Files" section,
there is also a link to a windows build of cnvgrib that John
Huddleston also provided.
