Depends on you definition of "build process". All the code from
bootstrap.jam through when you see the found# message happens in the jam
files. All that the code does up to that point is set up all the targets
and actions for those targets. After that bjam takes over and starts
header scanning, dependency analysis, target stability, and eventually
running of the needed actions.
