Hi,
Multiple occurrences are definitely allowed and handled.
If you do specify the option value to populate a container, and then pass the containerpointer to the add_options() method, you can later iterate over the options.
[...] Sorry, I should have been clearer. I know how to do multiple occurances of options that require a value, what I want though is multiple occurances of a switch. A single switch can be done with something like desc.add_options() ("verbose,v", bool_switch(), "increase verbosity"); but this fails with a multiple_occurrences exception if more than one -v option is supplied. Multiple boolean options can be done with something like desc.add_options() ("verbose,v", value<std::vector<bool> >(), "increase verbosity"); but this requires that each option is given a value, such as $ myprogram -v true -v true -v true which is not what I want. I want instead to be able to use a command line like $ myprogram -v -v -v Cheers, Ian
