Hi,

I'm trying to use the Program Options library to parse command line arguments
and config files.  I can do this with moderate success. I am currently
stuck on a
solution to the problem of unrecognized options that are present in a
config file.
It seems that parse_config_file() does not have an obvious way to not abort
reading a config file once it finds something that isn't declared in the options
description.

Any help on how to get around this (or just a kind of "hey you missed
this bit of
the manual" kind of pointer) would be very welcome.

Thanks,
         Kevin
