book style.
Please look at this version and tell me your opinion. Especially I don't feel
happy about the spacing and (not) indenting of paragraphs.
Also, I've removed things like "fax" and "letter" from the LaTeX mapping file.
SGMLtools happy.
The only symlink you need now is dist/birddoc -> dist/sgmltool. I'm
convinced it could be avoided by renaming the directory instead, but I'd
rather avoid it due to CVS pecularities.
