Hmm... I was not aware of that, and you did not tell that in previous
discussions. I think such automatic detection is very well possible.
There's one question though. In past, Jurgen said that at least for him it's
better to have everyting built in separate directories. Say, if bison
produces files to "bin", them "bjam --clean release" will clean those files
too, and he did not like this.
Do we need yet another option?
