   I'm issuing the same thing.
   @amagee Thanks for the hint.

   Meanwhile I was able to solve it this way:

   [manage.py]
   
   from flask.ext.script import Manager
   from werkzeug.serving import run_simple
   from app import app, register_blueprints
   
   # Factory app
   def create_app(config=None):
       if config:
           app.config.from_object("config." + config)
       else:
           app.config.from_object("config.default")
       return app
   
   # Create app 
   manager = Manager(create_app)
   manager.add_option('-c', '--config', help='Configuration')
   
   @manager.command
   def run():
       # Register blueprints
       register_blueprints(app)
   
       # Run WSGI application
       run_simple(
           app.config['HOST'], 
           app.config['PORT'], 
           app, 
           use_reloader=app.config['RELOAD'],
           use_debugger=app.config['DEBUG']
       )
   
   [app/__init__.py]
   # Define the WSGI application object
   # The app will be configured later.
   app = Flask(__name__)
   
   def register_blueprints(app):
       # Add (fake) admin blueprint 
       from app.admin.views import admin
   
       # Add the main app
       from app.main.views import apps
       app.register_blueprint(apps)
   

   Afterwards I can run:

   # python manage.py -c default run
   

   Edit:
   Have a look at https://github.com/dorneanu/crudappify/tree/master/apps/orgapp.

   @amagee that code would never work, since mycommand(app) is expecting a Flask object to be passed as a parameter in the shell, which is obviously impossible. You can only pass strings, which is all you see being passed in the example. Optional arguments (like url=None) need to be passed in the shell like this: --url=test.

   In your example, you either have to remove app from the parameter and instantiate it somewhere in the module instead of in a method, or declare app as global.
