 and theme module entry points, leaving the theme author to only have to worry
 about rendering code.
 
-Rendering functions (draw_*) that typically are overridden in GtkStyle are
-simply defined in a well-named static class (Maigre.Theme). All methods are
-optional. In addition to Draw functions, this class may optionally implement
-ModuleInit and ModuleExit functions.

 An example:
 
 using System;
-using Gtk;
-using Cairo;
 
-namespace Maigre
+public class MyTheme : Maigre.Theme
 {
-    public static class Theme
+    protected override void ModuleInit ()

+    }
