"""Container object that enables pluggable applications. A module can
be used to organize larger applications. They represent blueprints that,
in combination with a :class:`Flask` object are used to create a large
application.
A module is like an application bound to an `import_name`. Multiple
modules can share the same import names, but in that case a `name` has
to be provided to keep them apart. If different import names are used,
the rightmost part of the import name is used as name.
Here an example structure for a larger appliation::
/myapplication
/__init__.py
/views
/__init__.py
/admin.py
/frontend.py
The `myapplication/__init__.py` can look like this::
from flask import Flask
from myapplication.views.admin import admin
from myapplication.views.frontend import frontend
app = Flask(__name__)
app.register_module(admin, url_prefix='/admin')
app.register_module(frontend)
And here an example view module (`myapplication/views/admin.py`)::
from flask import Module
admin = Module(__name__)
@admin.route('/')
def index():
pass
@admin.route('/login')
def login():
pass
