I see many mails on this list on problems that have to do with understanding the basics of how jam work. (I'm one of them :) I agree very much with someone else who stated that it'd be very nice with some real-world examples. It'd also be very nice with rules in Jambase for building shared libraries. A strong point of Jam, in my opinion, is that the user gets to configure his compiler in the Jambase, and the actual Jamfiles just contain logical information of what sources are to be compiled into what libraries, executables, ...

With help from the mailing list archives I've managed to put together the following Jamfile. I've got two problems with it.

1. jam clean does not remove $(OUTDIR)

2. jam doesn't realize that the files (like debug/inspector.cpp) are in directories. Therefore it doesn't create the subdirectories to $(OUTDIR).
