And it's not alone in being undocumented.  Go to 
http://search.cpan.org/~ovid/Test-Harness-3.25/lib/App/Prove.pm#Attributes 
and note that 'rules' is one of over 40 attributes which are described 
as existing but are otherwise undocumented.

However, I see that 'rules' is the subject of testing in t/scheduler.t. 
  Do the individual tests in that file give you any clue as to how to 
proceed?

Thank you very much.
