Actually, I think you can setup through the mostly undocumented style_t enumeration for using
a "/" but it is not automatic as I recall. See  cmdline.hpp for the style_t definition. It also took a 
little looking to figure out how to set style_t. I did it once a couple of years ago and I forget offhand 
how I did it but could find it if needed.

  James,

  Hicham's point was to generate OS system dependent short long options notations. Like --help or -h on Posix and /help or /h on Windows. AFAIK, program options does not provide this feature.

  With Kind Regards,

    Try the syntax:

     desc.add_options()
       ( "help", "print help message\n" )
       ( "Long-Option-Name,o", ...);

    and then you have:
     --Long-Option-Name
    or
     -o
    as valid usages.
