+* Evolution internals.
+
+ Evolution can store its information locally (files for mail,
+ calendar and address book) or on a remote server (imap/pop,
+ cap, ldap).
+
+ Given the importance of syncing in this modern PDA world,
+ the Evolution GUI acts as a client to the data repository.
+ The data repository is a GUI-less CORBA server called Wombat.
+
+ Wombat provides a unified access system to the calendar and
+ addressbook data (doing mail is a bit hard, so we are leaving
+ this as a TODO item for now).
+
+ Wombat's CORBA interfaces are notifier-based. This means that
+ CORBA requests sent to Wombat do not return values
+ inmediately, but rather than for Wombat requests the user has
+ to provide a CORBA object that will be notified of what
+ happened.
+
+ Yes, that sounds hairy. It is actually pretty simple. It
+ basically means that you submit requests to Wombat, and a
+ callback is invoked in your code when the request has been
+ carried away.
+
+ This enables a Palm to sync to the repository without having
+ the GUI for Evolution running. It also means that volunteers
+ will be able to write text-based and web-based versions of
+ Evolution (not me though :-).
+
+* Evolution as a platform
+
+ Evolution is more than a client for managing the above
+ information: Evolution is a platform for building groupware
+ applications that use the above components to get their work done.
+
+ To achieve this Evolution is designed to be scriptable, and it
+ exports its internals trough CORBA/Bonobo. It is implemented
+ as a collection of Bonobo containers and Bonobo components.
+
+ There is a clean separation between the views (the user
+ interface) and the model (the view). The views that we are
+ writing are GNOME based, and they talk to the Wombat CORBA
+ server.

+ Wombat takes care of notifications to the various clients for
