…rgs are present Adds three new methods of `Arg` which allow for specifying three new types of rules. * `Arg::required_unless` Allows saying a particular arg is only required if a specific other arg *isn't* present. * `Arg::required_unless_all` Allows saying a particular arg is only required so long as *all* the following args aren't present * `Arg::required_unless_one` Allows saying a particular arg is required unless at least one of the following args is present.
Can now use the `App::before_help` method to add additional information that will be displayed prior to the help message. Common uses are copyright, or license information.
