Description: ========
        subparse
        ========
        
        A wrapper for argparse that provides decorator-based subcommand support.
        
        Commands can be defined separately from their actual main functions,
        enabling faster import times.
        
        Basic Usage
        ===========
        
        ::
        
            from subparse import CLI
        
            cli = CLI(version='0.0')
            cli.add_generic_option('--quiet', action='store_true',
                                   help='turn of debugging')
        
            @cli.command(__name__ + ':foo_main')
            def foo(parser):
                """
                a short description ending in a period.
        
                a longer description
                """
                parser.add_argument('--bar', action='store_true',
                                    help='turn on bar')
        
            def foo_main(app, args):
                pass
        
            args = cli.parse()
            app = MyApp(args)
            cli.dispatch(args, context=app)
        
        Lazy Decorators
        ===============
        
        Commands can be defined lazily and picked up later. This removes ordering
        restrictions between the commands and the cli object.
        
        ::
        
            # myapp/info.py
        
            from subparse import command
        
            @command('myapp.info:foo_main')
            def foo(parser):
                """perform foo"""
        
        ::
        
            cli = CLI()
            cli.load_commands('myapp.info')
        
        Entry Points
        ============
        
        Commands may also be defined in external modules and loaded via entry
        points.
        
        ::
        
            from subparse import cli
        
            cli = CLI()
            cli.load_commands_from_entry_point('myapp.commands')
        
        An extension application would then define the external module that should
        be searched for commands. Again this allows the commands themselves to be
        defined independently of the main functions, improving import speed.
        
        ::
        
            [myapp.commands]
            barpkg = barpkg.commands
        
        ::
        
            # barpkg/commands.py
        
            from subparse import command
        
            @command('barpkg.bar')
            def bar(parser):
                """perform bar"""
        
        ::
        
            # barpkg/bar.py
        
            def main(app, args):
                pass
        
        
        
        0.2 (2013-08-06)
        ================
        
        - Underscores in function names are converted to dashes in their respective
          subcommand names.
        - Add `CLI.add_generic_options` API.
        - Add a new `help` subcommand, allowing for `myapp help foo`.
        - Allow relative imports in the subcommand specification.
