 This package also enables to complete flags defined by the standard library `flag` package.
 To use this feature, simply call `complete.CommandLine` before `flag.Parse`. (See [./example/stdlib](./example/stdlib)).

 If flag value completion is desired, it can be done by providing the standard library `flag.Var`

 Instead of calling both `complete.CommandLine` and `flag.Parse`, one can call just `compflag.Parse`
