You can create a file named project-config.jam in Boost's source directory, too.

I personally find that putting configuration details into a file is superior
approach compared to zillion of options or environment variables. Say, if you
build a project with automake with zillion of configure options, those options
are put directly in Makefile, in your build dir, so if you remove your build tree,
you have to re-figure those options next time you build.

In fact, this is a flaw shared by CMake -- if you configure some project as:

   cmake -Dfoo=blah -DBOOST_ROOT=whatever ../src

it helpfully puts those options into the cache file. Unfortunately, when the
configure magic confuses itself (which does happen), your only solution is to
remove the cache, and then you need to recall and pass the same options again.
