I though about this too.. but if directory name is too long the nice --version
output becomes cluttered.

Almost the same.

Yea, it can be as verbose at it likes. Ok, implemented the following:

bash-2.05b$ bash-2.05b$ /tmp/bjam --debug-configuration
notice: found boost-build.jam
at /home/ghost/Work/boost/tools/build/v2/example/boost-build.jam
notice: loading Boost.Build from /home/ghost/Work/boost/tools/build/v2/kernel

Gonna commit now.
