SUMMARY [Bruno] ?

Hi everyone,

James Higgo suggests to me that I put in a SUMMARY thread
an answer I give him (in a private discussion).

It is no so much a summary than an oversimplification on
what I try to explain.

But may be it can help to clarify the measure and reversal point.

Sure - why not submit it to the list as part of the suggested SUMMARY
series, which can one day be compiled into the FAQ. I'm off-loine now until
Monday.
Regards,
James
