Update

I have just finished checking in a bunch of changes to the build system.

A bunch of new core behavior was added and documented in
tools/build/build_system.htm. The foundations of the new build system have
been implemented in tools/build/new/*. Please see tools/build/new/readme.txt

A summary of changes is appended.

I have also uploaded some elisp for editing jam and for following its debug
output to the files area at http://groups.yahoo.com/group/jamboost/files/.
This stuff is actually making it easy for me to work with Jam ;-). If you
need help getting set up, please ask me.
