Specifying the Short Form of an Option Name

To specify the short form of an option name, set the shortName element of the @Param annotation to a single character that specifies the short form of the parameter. The user can specify this character instead of the full parameter name, for example -m instead of --monitor. If you do not set this element, the option has no short form.
