Correct way of determining project root

If I have a project tree

root
root/test

and i wish to specify <include>root in the Jamfile in root/test, what is the best way of doing this (with the current jam version)

I have tried adding MY_ROOT =? $(TOP) to Jamrules, and then <include>$(MY_ROOT), but that seems to give a relative directory which is incorrect when jam is invoked from the root/test subdirectory.

Any suggestions ?
