10 | *\brief Hachti's wonderful commandline parser. |
11 | * |
12 | * This class is designed to do all the work with the parameters passed to |
13 | * the main() routine of a program.\n |
14 | * Usage:\n |
15 | * - Create an instance. |
16 | * - Add Parameters/switches with add_param(). |
17 | * - Add Arguments with add_argument(). |
18 | * - Call read_args() with your main routine's arguments.\ |
19 | * The vector returned by read_args() contains all error \ |
20 | * messages. When it's empty, everything is fine! |
21 | * - Call get_help() if you want nice formatted help output. \ |
22 | * (You want!!!) |
23 | * Sould be easy to use..... Enjoy. |
