-Summary

 Core Functionality
-^^^^^^^^^^^^^^^^^^
+------------------
 
 The :mod:`argparse` module's support for command-line interfaces is built
-from the following:
-
-The :class:`argparse.ArgumentParser` creates a new :class:`ArgumentParser`
-object. Commonly used arguments include prog_, description_, and
-formatter_class_. For example, the user can create an instance of
-:class:`ArgumentParser` through the following::
-
-   >>> parser = argparse.ArgumentParser(prog='PROG', description='DESC',
-   ...                                  formatter_class=argparse.RawDescriptionHelpFormatter)
-
-The :func:`ArgumentParser.add_argument` is a function that is used
-to define how a single command-line argument should be parsed. Commonly used
-arguments include `name or flags`_, action_, default_, type_, required_,
-and help_. An example of the function :func:`ArgumentParser.add_argument`
-is as follows::
-
-   >>> parser.add_argument('-v', '--verbose', action='store_true',
-   ...                     help='Show various debugging information')
+around an instance of :class:`argparse.ArgumentParser`.  It is a container for
+argument specifications and has options that apply the parser as whole::
 
+   parser = argparse.ArgumentParser(
+                 prog = 'ProgramName',
+                 description = 'What the program does',
+                 epilog = 'Text at the bottom of help')
 
-Basic Usage of :func:`add_argument`
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The :func:`ArgumentParser.add_argument` function attaches individual argument
+specifications to the parser.  It supports positional arguments, options that
+accept values, and on/off flags::
 
+   parser.add_argument('filename')           # positional argument
+   parser.add_argument('-c', '--count')      # option that takes value
+   parser.add_argument('-v', '--verbose',
+                       action='store_true')  # on/off flag
 
-**Name or Flags Type**
+The :func:`ArgumentParser.parse_args` function runs the parser and puts
+the extracted data in a :class:`argparse.Namespace` object::
 
-====================== ===========================
-Type                   Example
-====================== ===========================
-Positional             ``'foo'``
-Optional               ``'-v'``, ``'--verbose'``
-====================== ===========================
+   args = parser.parse_args()
+   print(args.filename, args.count, args.verbose)
