A "way" is different to a "route". We need a path for found a specific resource, but we need a way for do something. This library follow this concept when implements the routing and control of PHP application.
Ways is a class that adapts the concept of SOA to the architecture of a PHP application, and tries to integrate the parts of a hybrid system.
With Ways you should think more about "control points" than on controllers of an MVC pattern. Control points are activated when they are needed, ie on demand, depending on the definition you have made.
