```but ebook usually means a PDF which would be all right if the text
didn't contain specialist symbols.
The publishers weren't very helpful when I contacted them. According
to the "lady" on the phone they didn't even have the latex source code.
I'll probably try again. Hopefully this time I'll get someone more
reasonable to deal with.
Cheers,
Paul
