Could we keep this more generic and not mention platform specific
things like PURR?

Not sure if I follow.  PURR will be used/displayed if available.  Time
based statistics will always be available.

I can change the description to make this clear.  Or, are you asking
that this not be mentioned at all?  Based on previous discussions, I
added the ability to display both wall and cpu time if available.

Thanks,
