+Blender Data Structures:
+------------------------
+
+Programs manipulate data structures.  Blender python scripts are no exception.
+Blender uses an Object Oriented architecture.  The bpython interface tries to
+present Blender objects and their attributes in the same way you see them through
+the User Interface ( the GUI ).  One key to bpython programming is understanding
+the information presented in Blender's OOPS window where Blender objects and their
+relationships are displayed.
+
+Each Blender graphic element ( Mesh, Lamp, Curve, etc.) is composed from two parts:
+An Object and ObData. The Object holds information about the position, rotation and size
+of the element.  This is information that all elements have in common.  The ObData holds
+information specific to that particular type of element.  
+
+Each Object has a link to its associated ObData.  A single ObData may be shared by many Objects.  A graphic element also has a link to a list of Materials.  By default, this list is associated with the ObData.
+
+All Blender objects have a unique name.  However, the name is qualified by the type of the object.  This means you can have a Lamp Object called Lamp.001 ( OB:Lamp.001 ) and a Lamp ObData called Lamp.001 ( LA:Lamp.001 )
+
+For a more in-depth look at Blender internals, and some understanding of why
+Blender works the way it does, see the U{Blender Architecture document<http://www.blender3d.org/cms/Blender_Architecture.336.0.html>}.
