Programming with the Extensions Manager

About a week ago I published my Extensions Manager, a Tridion 2011 extension that allows extensions’ creators define customizations for their users in a few lines of code. The customizations are exposed as fields to the users in a graphical interface that is easy to use and also takes care of the persistence of the values the users enter.

In my previous post I focused on the functional side of the Manager, the different features it has and the visual interaction.
In this post I’d like to focus on the programmatic side – how should an extension creator use it.
