-/**
- * class Action
- *
- * Base class for all actions
- * Do not call in your code, use this class only for inherits your own action
- *
- * Information about how to convert command line strings to Javascript objects.
- * Action objects are used by an ArgumentParser to represent the information
- * needed to parse a single argument from one or more strings from the command
- * line. The keyword arguments to the Action constructor are also all attributes
- * of Action instances.
- *
- * ##### Allowed keywords:
- *
- * - `store`
- * - `storeConstant`
- * - `storeTrue`
- * - `storeFalse`
- * - `append`
- * - `appendConstant`
- * - `count`
- * - `help`
- * - `version`
- *
- * Information about action options see [[Action.new]]
- *
- * See also [original guide](http://docs.python.org/dev/library/argparse.html#action)

-/**
- * new Action(options)
- *
- * Base class for all actions. Used only for inherits
- *
- *
- * ##### Options:
- *
- * - `optionStrings`  A list of command-line option strings for the action.
- * - `dest`  Attribute to hold the created object(s)
- * - `nargs`  The number of command-line arguments that should be consumed.
- * By default, one argument will be consumed and a single value will be
- * produced.
- * - `constant`  Default value for an action with no value.
- * - `defaultValue`  The value to be produced if the option is not specified.
- * - `type`  Cast to 'string'|'int'|'float'|'complex'|function (string). If
- * None, 'string'.
- * - `choices`  The choices available.
- * - `required`  True if the action must always be specified at the command
- * line.
- * - `help`  The help describing the argument.
- * - `metavar`  The name to be used for the option's argument with the help
- * string. If None, the 'dest' value will be used as the name.
- *
- * ##### nargs supported values:
- *
- * - `N` (an integer) consumes N arguments (and produces a list)
- * - `?`  consumes zero or one arguments
- * - `*` consumes zero or more arguments (and produces a list)
- * - `+` consumes one or more arguments (and produces a list)
- *
- * Note: that the difference between the default and nargs=1 is that with the
- * default, a single value will be produced, while with nargs=1, a list
- * containing a single value will be produced.
