 on POSIX, the --help option is typically used for printing usage
 information.
 on Windows, the /? is the typical option for that.

 It would be cleaner if the user could check with some function whether the
 <help option> is set or not instead of explicitly checking for the "help"
 string
 {{{
    if (vm.count("help"))
 }}}

 to decide when to print usage information.
