These are suggestions for component-based tutorials
These are aimed at platform developers who want to work below the level of app developers (e.g. add a new panel to MeeGo netbook, integrate with the MeeGo desktop better, use Mx or Clutter directly).
So they cover libraries and services which don't have Qt wrappers and which are unlikely to get them, but which are core to MeeGo.
DBus is core here, as it's used for IPC on MeeGo but isn't explained very well anywhere.
Tracker is another area which needs documentation. It may be documented elsewhere, but not in the MeeGo context much.
libsocialweb is important for netbook, but doesn't seem to be core across verticals. It is barely documented.
Clutter has some decent documentation, but Mx has the bare minimum, with some parts of the API being largely undocumented (like MxOffscreen).
What's very often lacking is task-oriented "how" documentation at the application level: how do I create a window? how do I animate an application between two states? how do integrate with the desktop and menu system?
