I did some manual labor this weekend, and converted the Scala SBT tool documentation into PDF format (a PDF file). I also tried to contact the SBT author, Mark Harrah, to see if he wanted the PDF on the Github website, but I couldn't find any way to email him through Github, so ...
If you want a copy of the Scala SBT documentation in PDF format, current as of June 3, 2012, here it is:

We're actually aiming to get the PDF generated and into the distribution downloads! Glad to see we're not the only ones who want that :)
