Thanks for the quick feedback.  I'll make all you suggested changes, but need to think a little more about `diagtool`.

+    if not os.path.exists(diagtool):

+        return

The problem is that `diagtool` contains a map of DiagID -> DiagEnums, and must be in sync.   I wasn't sure how else to enforce the version you were using was built at the same time as the code you're trying to debug.

I can add the option, but then you might get bogus output.
