I think only the *.hpp files should be installed.
Also, installation on Unix might want to change the
suffixes (or at least make it configurable for all
platforms). Everything else sounds great.

If we were to do this, we would need to synch the
releases of the packages with the release of Boost.
I'm not sure if it would be good to be limited in this
I guess an alternative would be to have packages adopt
the boost release number (eg 1.27.0) and use a fourth
digit for bug-fix releases (eg 126.96.36.199).

This is great work. I hope it gets built on.
