Hi,
Is there some way to say
bpo::options_description desc("Allowed options");
        desc.add_options()
        ("method",
bpo::valuestd::string()->allowed_values("foo")("bar"), "" )
so I donøt have to reject the arguments manually?
Thanks

Can you try using regex to cut off options?
That would be a good idea. I think it would also be cool if we could 
simply say

   po::valuestd::string()->match( "some regex expression here" );

It so common to do this kind of validation that I think it would be a 
benefit if the library could handle this. It should be possible to
let the library depend on boost.regex only when needed.
