[plt-scheme] scribble --pdf a collection?

I can use setup-plt to build the Scribble docs for a collection or 
PLaneT package but is there a similar convenient way I can build its 
docs as a PDF?

For example, the Web Server manual is big enough that I'd like to print 
it out, but it has so many separate pages that this is a pain to do 
manually. (And a PDF would probably print better anyway.)

Thanks,
Dave
