I've added a first cut to the sandbox at pdf/units/release/units (https://svn.boost.org/svn/boost/sandbox/pdf/units/release/units.pdf ) using a patched version of your Jamfile (let me know if you want me to commit the attached patch).
Thanks - the patch looks fine to me, if you don't mind committing it...
* The PNG images don't look that good in PDF's, we have the ability to embed SVG's or PDF's (haven't tried the latter though) if you want to improve these: but it would require some editing of the quickbook source.
I'll take a look at this and see how easily I can generate SVG images from LaTeX source; PDFs should be easy to generate, so perhaps I should try that first...
Also if you want the page setup options changed/tweaked let me know as now I've got it working I can regenerate it pretty quickly...
Thanks again. I'll take a look at the generated PDF and get back to you. Matthias
