.. _index: defcon ====== defcon is a set of UFO based objects optimized for use in font editing applications. The objects are built to be lightweight, fast and flexible. The objects are very bare-bones and they are not meant to be end-all, be-all objects. Rather, they are meant to provide :ref:`base functionality ` so that you can focus on your application's behavior, not :ref:`object observing ` or :ref:`maintaining cached data `. Basic Usage ^^^^^^^^^^^ defcon is very easy to use:: from defcon import Font font = Font() # now do some stuff!
