 It would be nice to allow support for boost::optional<T> arguments in
 program_options, so you can write following:

 {{{
 #!div style="font-size: 100%"
   {{{#!cpp
 optional<std::string> optionalArg;
 options_description   desc("allowed options");
 desc.add_options() ("optional", value(&optionalArg), "specify optional
 argument");
   }}}
 }}}

 And shouldn't bother with argument checking using variables_map.
