| + | This class makes handling argc, argv (as supplied by main() i.e.) very easy. After initializing you provide it with an option you would like to have and an optional default value. If the option is found inside argv it will be returned to you, if not you get the default value. Reading an option from the argument list removes it from the argument list. It works like a stack with a find-and-pop function. | ||
| + | |||
| + | Instead of using argc, argv you can also supply a vector of strings. This comes in handy if you have a line that was splitted into tokens by [[split_line]] for example. | ||

| + | == Remarks == | ||
| + | * you cannot unset a flag with something like -flag 0. You will have to test for another flag i.e. -notflag. | ||
| + | * -option=5 will not be recognized. There is no internal splitter. | ||
| + | * every option takes exactly 1 argument. | ||
