Patrick,
Sorry to keep posting new versions but I found another problem with my
previous one, which is that there's no ppmtopng command, so I had to add
another if-then statement to fix it. I also learned a couple of things
from your script that are very useful (e.g. accepting equally "yes," "Y"
or "y") and changed the prompt to a more usual style: from (yes/no) to
(y/N).
I've now tried all variations and they all work. Now if you can
integrate your mods to accept arguments at the command line that'd be
sweet. Thanks for being interested in this :)
Jon
