Simple Example of Blender2.5 Python scripts

Following example of Python code adds cube to the scene. It has several flaws, but it could be helpful to someone. This works with Blender 2.5 beta (2.55.0).

# Add vertices

# Create new object and link mesh data to it
obj = bpy.data.objects.new("Cube", mesh)
# Link object to current scene
bpy.context.scene.objects.link(obj)
