Hi Jeff and Kaspar,

Thanks for your responses.  At first blush,  they don't seem to do what I
had in mind.  However, they have Ruby constructs I haven't dealt with,  so I
need to read their documentation and "play" with them a little.  I've got to
travel for the next couple of days,  so I'll take along my Ruby books and
print-outs of your missives.  I'll post back later in the week either
reporting I've had an "Aha! moment" or seek additional comments.

Again,  thanks for posting.

Regards,
Richard
