Hello, All!

I have problem with process_jam_log tool. It requires
  to define relativeness from project root with rule
"subproject". But in case I'm building mine project
out of location on BOOST_ROOT the rule is unknown
and have this error:

 >..\test\Jamfile:3: in modules.load
 >rule subproject unknown in module 
 >Jamfile</H:/tmp/Boost/Tutorials/sample1/test>.

How can I enable the subproject rule in mine project?

Best Regards,
