Ah.  I had thought that it would launch a GUI which would allow me to
select from a set of pre-defined actions ...  The real problem is that
the diagnostic  does not appear if one launches TLMGR from a Windows
Explorer file listing, as I did.  It was only when I edited the first
line to read "Echo on" that I was able to read and report the diagnostic.
