contain rules which are evaluated against each dependency of the package in
question.

Evaluation starts with the rules file closest to the package.  If that file
makes a determination to allow or forbid the import, evaluation is done.  If
the import does not match any rule, the next-closest rules file is consulted,
and so forth.  If the rules files are exhausted and no determination has been
made, the import will be flagged as an error.
