Re: [jamboost] <lib> broken?

No, the bug is that somebody broke something!

The original behavior of boost.build was to load any not-completely-read
Jamfiles of dependencies with main target generation disabled so that it
could collect the dependency info. That means that you can define lib
dependencies after their dependents in the same jamfile -- it would
re-include the jamfile to gather up the dependencies, then continue
generating main targets.
