5) Ideally it should be eventually be possible to automatically create a PDF book of "The Boost Libraries V#.##" which one could download and/or print out. Heck, at that point Boost could even sell dead-tree copies of it to help cover whatever operating costs the Boost organization might have (assuming this is compatible with Boost's goals).
There are PDF's downloadable from here: http://sourceforge.net/projects/boost/files/boost-docs/ but note that these downloads don't cover all of Boost (just those libraries that use Quickbook/Boostbook/Docbook for their documentation). A complete "all of Boost" PDF would be a monumentally large document and a non starter IMO, as for a print version, well it would probably require a whole tree per copy ;-) HTH, John.
