What's the reason for having them in the repository then, in the first place ?
Can't flex be made a precondition for compiling ? How does boost.build decide
whether it the cpp is up to date ?

I'm asking also because I have noticed last week that some html is in the
repository, even though the sources (qbk) it is made from is there, too.

What are the guidelines for what belongs into the repository and what not ?
