-The Highest Level
-~~~~~~~~~~~~~~~~~
-index.php takes care of loading the globals:
-
-$config -- some variety of Config class
-$database -- a class used to get raw SQL access
-$page -- a GenericPage object, a data structure which holds all the page parts
-$user -- the currently logged in User
-
-then it sends an InitExtEvent and PageRequestEvent, these can each trigger
-more events of their own.
-
-Once the chain of events comes to an end, the $page object is passed
-to the theme's layout.class.php to be turned into HTML
-
-
-Events and Extensions
-~~~~~~~~~~~~~~~~~~~~~
-An event is a little blob of data saying "something happened", possibly
-"something happened, here's the specific data". Events are sent with the
-send_event() function.
-
-An extension is something which is capable of reacting to events. They
-register themselves using the add_event_listener() command. (Although for
-subclasses of SimpleExtension, registration is handled automatically).
-
-
-Themes
-~~~~~~
-Each extension has a theme with a specific name -- the extension Cake which
-is stored in ext/cake/main.php will have a theme called CakeTheme stored in
-ext/cake/theme.php. If you want to customise it, create a class in the file
-themes/mytheme/cake.theme.php called CustomCakeTheme which extends CakeTheme
-and overrides some of its methods.
-
-Generally an extension should only deal with processing data; whenever it
-wants to display something, it should pass the $page data structure along
-with the data to be displayed to the theme object, and the theme will add
-the data into the page.

+ * SCore is a framework designed for writing flexible, extendable applications.
+ * Whereas most PHP apps are built monolithicly, score's event-based nature
+ * allows parts to be mixed and matched. For instance, the most famous
+ * collection of score extensions is the Shimmie image board, which includes
+ * user management, a wiki, a private messaging system, etc. But one could
+ * easily remove the image board bits and simply have a wiki with users and
+ * PMs; or one could replace it with a blog module; or one could have a blog
+ * which links to images on an image board, with no wiki or messaging, and so
+ * on and so on...

  * There are a bunch of Extension subclasses, they talk to eachother by sending
  * and recieving Event subclasses. The topic of conversation is decided by the
  * initial PageRequestEvent, and each extension puts its notes into the shared
  * Page data store. Once the conversation is over, the Page is passed to the
  * current theme's Layout class which will tidy up the data and present it to
