- * @defgroup libfast libfast
- * @{
- * FastCGI Application Server w/ templates.
- *
- * Libfast is a framework to write web applications in an MVC fashion. It uses
- * the ClearSilver template engine and communicates through FastCGI with
- * the webserver. It is multithreaded and really fast.
- *
- * The application has a global context and a session context. The global
- * context is accessed from all sessions simultaneously and therefore
- * needs to be threadsave. Often a database wrapper is the global context.
- * The session context is instanciated per session. Sessions are managed
- * automatically through session cookies. The session context is kept alive
- * until the session times out. It must implement the context_t interface and
- * a #context_constructor_t is needed to create instances. To each session,
- * a set of controllers gets instanciated. The controller instances are per
- * session, so you can hold private data for each user.
- * Controllers need to implement the controller_t interface and need a
- * #controller_constructor_t function to create instances.
- *
- * A small example shows how to set up libfast:
- * @code
- dispatcher_t *dispatcher;
- your_global_context_implementation_t *global;
-
- global = initialize_your_global_context();
-
- dispatcher = dispatcher_create(NULL, FALSE, 180,
- (context_constructor_t)your_session_context_create, global);
- dispatcher->add_controller(dispatcher, your_controller1_create, param1);
- dispatcher->add_controller(dispatcher, your_controller2_create, param2);
-
- dispatcher->run(dispatcher, 20);
-
- dispatcher->waitsignal(dispatcher);
-
- dispatcher->destroy(dispatcher);
- global->destroy();
- @endcode
