I guess Simon will respond for himself, but I was under the impression
that he could not run SNNS at all, i.e. rc_image had somehow grabbed too
much.

David had previously told me about this and I had copied it over.
Alas it doesn't work with Poplog V14.2. I have been delaying changing
to V14.5 for various reasons, though I hope to order it before long.

Which reminds me I wonder how other people feel about the new V14.5
formats for online documentation? They are obviously nicer for reading
online, but a lot of people like to print such files and read them
offline and in my limited experience this now causes problems.

Does someone have a nice utility for converting the new documentation
files to a format that will print nicely, on both postscript and
non-postscript printers. I fear lack of printability is a very serious
problem for students.
