Hello Michael:

If you want no positional options to be allowed you can refer to this
answer:
http://stackoverflow.com/questions/3858251/parsing-positional-arguments/3859400#3859400

To parse a multi-token value correctly you should call special member
function of a PO option.
PO option is of type boost::program_options::typed_value<T>, it has a
member function multitoken().
multitoken() should be called before adding an option to PO set of
functions. Value type should be std::vector<T> then.

Regards,
Dmitriy Matison.
