Hi Noel,

after fixing a minor typo in the attached code I'm getting

  rule path.find-directory-containing unknown in module jag_swig

and really there is no such rule in path.jam.

Do you think that this mechanism is going to work even for a .jam file
(i.e. a utility file that is not a project) that has no parent
Jamroot?

Thanks,
