Yes, Tobias has mailed me+Craig about his latest stuff and I haven't had a chance to incorporate it yet. It's on the to-do list, though...

Not yet. Hopefully soon.

Did the same with a couple of files in the use-mpi-tkr and use-mpi-ignore-tkr directories, and use-mpi-tkr/ (One editor command each.)

Cool. Any chance you could send us a patch?
