[Boost-users] program options config file format?

Hi About a week ago Mathias Kaepler posted the following question:

Hi,

the program_options reference talks about being able to parse config files, but doesn't mention a thing about its layout. No examples are shown how a file has to look like to be parsable by program_options.

Any ideas? Besides the layout, which characters are treated as comments? .

I have exactly the same question but have not been able to find the response that was given to Mathias. Would someone share it with me? thanks, Glen Stark
