But nowhere in the documentation does it say how to pass this to the parser! Given the code based on the documentation samples,

po::store(po::parse_command_line(argc,argv,opt),vm); po::notify(vm);

and

po::positional_options_description pd; pd.add("output-file", 2).add("input-file", -1);

where do I tell parse_command_line about pd?

Add a ".positional(pd)" to the parser component. It appears in the tutorial, here: http://www.boost.org/doc/libs/1_44_0/doc/html/program_options/tutorial.html (see the sample in the Option Details.)
