+ * 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]]

+ * 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.
