Thanks. That sure dumps a boatload of data. I get about 604K lines, so 
I'm not quite sure what I'll need to pick out of it. For example, in the 
(partial) output below the substring within the <p...> tag seems in some 
cases to be the directory containing the Jamfile, but in others is a 
directory in the object tree.

Does the MPIH-object sub-string indicate that path is the project 
directory? In this simple case I only get one unique substring with 
MPIH-object in it, but in the full output some directories have it 
multiple times (each with different @XXXXX values.)
