Code structure
==============

The new wikigraphe (> 0.3) is based on a Model-View-Controler
architecture. We have tried to reflect this architecture in the source
code layout.

 * control: the controlers
 * model: the models
 * view: the views

Extra directories were required to complete certain functions or
simplify things:

 * conf: configuration
 * data: files repository
 * data/images: repository for the wikigraphe's images
 * js: javascript files (not in view to shorten urls)
 * model/schemas: database schemas
 * tpl: the view templates (to shorten urls again)
 * lib: common php libraries
 * index.php: a broker that calls the right view
