    really install swfdec_as_frame.h and document it
    
    Woohoo, everything documented!

+ * SECTION:SwfdecAsFrame
+ * @title: SwfdecAsFrame
+ * @short_description: information about currently executing frames
+ *
+ * This section is only interesting for people that want to look into
debugging.
+ * A SwfdecAsFrame describes a currently executing function while it is
+ * running. On every new function call, a new frame is created and pushed on
top
+ * of the frame stack. To get the topmost one, use 
+ * swfdec_as_context_get_frame(). After that you can inspect various properties
+ * of the frame, like the current stack.
+ *
+ * a #SwfdecAsFrame is a #SwfdecAsObject, so it is possible to set variables on
+ * it. These are local variables inside the executing function. So you can use
+ * functions such as swfdec_as_object_get_variable() to inspect them.
