PDF version of D manuals

[Walter Bright]

I've been taking some heat lately about the D web site not making 
available a PDF version of the D manual that can be downloaded, printed, 
and read offline.

I know some people have made PDFs of the manual before. The trouble is, 
they rapidly go out of date.

So I'm interested in if anyone can recommend a tool that can take text 
and convert it to PDFs. I'm not interested in a tool with a gui 
interface, I want one that can be driven from a script, so this can be 
done automatically with each new release.

(The html version of the manual is currently created automatically using 
a script from Ddoc text files. Such has really cut the workload of 
maintaining a common look/feel of the site.)
