This might be off topic, but I'm really lost here. What I do on my system here is to set directory libs/serialization/test as the current directory. Then I invoke bjam, process.., and library_status or compiler status to generate the test report the one library I'm interested in. bjam dependency (generation or tracking) makes sure that any prerequisite libraries are rebuilt. (maybe there should be an option to re-test those prerequisite builds). Why not just apply this process to each library? It's a lot simpler than trying to maintain and "customize" a "global view" with an array of command line options and doesn't require any more work to make the libraries "more modular". Also it has the benefit what when I muckup my Jamfile.v2, It doesn't crash the whole testing setup. Robert Ramey
