[Boost-users] program_options: change output format?

Is there a way to change the output format that program_options::options_description uses for operator<<? I don't like the output format it uses by default, and I'd like to use the usual GNU format instead. Alternatively, is there a relatively easy way to iterate over all the entries in an options_description (which can be nested, I gather) in a way that I could print the help output myself? From looking over the interface, it seems that there's not really enough information exposed (via the public interface) to do this -- e.g., the "short name" of an option_description is private, and there doesn't seem to be any way to get access to the "groups" in options_descriptions. Thanks, -Miles -- Would you like fries with that?
