Essentially, you should forget about project-root.jam For top-level directory 
you should use Jamroot, and for other directories -- Jamfile.

What made you think that main target rule is called "main-rule". Do the docs 
say that?

At least at http://boost.org/boost-build2/doc/html/bbv2/extending/rules.html
it's said that declaration of type OUTPUT will create main target rule called
"output". "main-rule" is a name of action, and is not related to the name of 
main target rule.
