-
-History
--------
-
-Before (and including) argparse 1.1, the argparse package was licensed under
-Apache License v2.0.
-
-After argparse 1.1, all project files from the argparse project were deleted
-due to license compatibility issues between Apache License 2.0 and GNU GPL v2.
-
-The project repository then had a clean start with some files taken from
-Python 2.7.1, so definitely all files are under Python License now.

-"""Command-line parsing library
-
-This module is an optparse-inspired command-line parsing library that:
-
-    - handles both optional and positional arguments
-    - produces highly informative usage messages
-    - supports parsers that dispatch to sub-parsers
-
-The following is a simple usage example that sums integers from the
-command-line and writes the result to a file::
-
-    parser = argparse.ArgumentParser(
-        description='sum the integers at the command line')
-    parser.add_argument(
-        'integers', metavar='int', nargs='+', type=int,
-        help='an integer to be summed')
-    parser.add_argument(
-        '--log', default=sys.stdout, type=argparse.FileType('w'),
-        help='the file where the sum should be written')
-    args = parser.parse_args()
-    args.log.write('%s' % sum(args.integers))
-    args.log.close()
-
-The module contains the following public classes:
-
-    - ArgumentParser -- The main entry point for command-line parsing. As the
-        example above shows, the add_argument() method is used to populate
-        the parser with actions for optional and positional arguments. Then
-        the parse_args() method is invoked to convert the args at the
-        command-line into an object with attributes.
-
-    - ArgumentError -- The exception raised by ArgumentParser objects when
-        there are errors with the parser's actions. Errors raised while
-        parsing the command-line are caught by ArgumentParser and emitted
-        as command-line messages.
-
-    - FileType -- A factory for defining types of files to be created. As the
-        example above shows, instances of FileType are typically passed as
-        the type= argument of add_argument() calls.
-
-    - Action -- The base class for parser actions. Typically actions are
-        selected by passing strings like 'store_true' or 'append_const' to
-        the action= argument of add_argument(). However, for greater
-        customization of ArgumentParser actions, subclasses of Action may
-        be defined and passed as the action= argument.
-
-    - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,
-        ArgumentDefaultsHelpFormatter -- Formatter classes which
-        may be passed as the formatter_class= argument to the
-        ArgumentParser constructor. HelpFormatter is the default,
-        RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser
-        not to change the formatting for help text, and
-        ArgumentDefaultsHelpFormatter adds information about argument defaults
-        to the help.
-
-All other classes in this module are considered implementation details.
-(Also note that HelpFormatter and RawDescriptionHelpFormatter are only
-considered public as object names -- the API of the formatter objects is
-still considered an implementation detail.)

-    all attributes of Action instances.
-
-    Keyword Arguments:
-
-        - option_strings -- A list of command-line option strings which
-            should be associated with this action.
-
-        - dest -- The name of the 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.  Other values include:
-                - 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.
-
-        - const -- The value to be produced if the option is specified and the
-            option uses an action that takes no values.
-
-        - default -- The value to be produced if the option is not specified.
-
-        - type -- The type which the command-line arguments should be converted
-            to, should be one of 'string', 'int', 'float', 'complex' or a
-            callable object that accepts a single string argument. If None,
-            'string' is assumed.
-
-        - choices -- A container of values that should be allowed. If not None,
-            after a command-line argument has been converted to the appropriate
-            type, an exception will be raised if it is not a member of this
-            collection.
-
-        - required -- True if the action must always be specified at the
-            command line. This is only meaningful for optional command-line
-            arguments.
-
-        - help -- The help string describing the argument.
-
-        - metavar -- The name to be used for the option's argument with the
