 // Switches can optionally have a value attached using an equals sign,
 // as in "-switch=value".  Arguments that aren't prefixed with a
 // switch prefix are considered "loose parameters".  Switch names are
 // case-insensitive.  An argument of "--" will terminate switch
 // parsing, causing everything after to be considered as loose
