In my Jamroot.jam, I have:

project apago : build-dir ../bbuild ;

So it builds everything in a directory outside the source tree.  I don't
know if that helps you, but it avoids having to type it on the
command-line.  If the Jamroot.jam were in /usr/src, e.g., it would build
everything in /usr/bbuild.

Also, I put my "using gcc ;", etc., in my Jamroot.jam as well, depending
on the OS I'm running on.
