It is up to the developer to choose the tools and +libraries they want to use.

This name is used to find resources + on the filesystem, can be used by extensions to improve debugging + information and a lot more. + + So it's important what you provide there. If you are using a single + module, `__name__` is always the correct value. If you however are + using a package, it's usually recommended to hardcode the name of + your package there. + + For example if your application is defined in :file:`yourapplication/app.py` + you should create it with one of the two versions below:: + + app = Flask('yourapplication') + app = Flask(__name__.split('.')[0]) + + Why is that? The application will work even with `__name__`, thanks + to how resources are looked up. However it will make debugging more + painful. Certain extensions can make assumptions based on the + import name of your application. For example the Flask-SQLAlchemy + extension will look for the code in your application that triggered + an SQL query in debug mode. If the import name is not properly set + up, that debugging information is lost.
