I noticed some recent activity on the list by the author of
boost::program_options, so I'm posting this one more time.
Thank you.

Just a follow up: I did not receive any response to my
query below (neither from the list, nor from the library author, whom I
attempted to contact directly).
Can anyone give me an idea of the general status of
boost::program_options? Is it still being maintained? Am I the only
person using it ? :)
Thanks,
MD
