Re: [Boost-users] Question about program_options

I use it. Very nice when developing Win32 apps cross platform with anything else. Thanks again boost and whoever wrote this lib. -Chris On 8/10/06, Drumheller, Michael wrote:

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
