Re: errors with AMWG diagnostic package

Hi Mary and Evelyn.

Thanks for you replies on this. I was out of town for an extended 4th
of July weekend. Turns out that I forgot that the AMWG script needs
to have the output file type set to postscript instead of pdf anyways
if you want to generate the web pages, which I do. I had just
neglected to change this in the new version of the main csh script in
the package.

Thanks again for your help!
Mark
