Pyramid add-on for facilitating UI layout
Pyramid Layout is an add-on for the Pyramid Web Framework which allows developers to utilize the concept of a UI layout to your Pyramid application. Different layouts may be registered for use in different contexts of your application. The concept of panels is also introduced to facilitate rendering of subsections of a page in a consistent way across different views in a reusable way.
