PDF version of D manuals

[Mars]

If you are interested in a more elaborate solution than a simple 
html2pdf script take a look at the system developed for the FreeBSD 
project. Documentation (books, articles, the website, etc.) is written 
in DocBook format (SGML) and html, text, pdf, etc, versions are 
generated from it. It works really well.
