Animation using Blender's Python Interface

Not sure whether to ask this here or in the Development forum. I have a few hundred objects in Blender that I want to animate, these were generated using Blender's Python interface. While mesh modeling with this interface is pretty straightforward, I can't find a decent tutorial covering animation with it anywhere. Can anyone point me in the direction of one?

I've put a very basic script together if anyone's interested in learning the programming side of Blender and is stuck like I was a couple of days ago. Nothing particularly exciting - it rotates a cube, but I'm chuffed to get at least something working

It's probably over-simplified and may have a few faulty assumptions, but it works for me on Blender 2.49.

import Blender
import bpy
import math

scene = bpy.data.scenes.active

context = scene.getRenderingContext()
context.fps = 30
context.sFrame = 0
context.eFrame = 60
context.sizeX = 640
context.sizeY = 480

vertices = [[-1.0, -1.0, -1.0],
            [-1.0, -1.0,  1.0],
            [ 1.0, -1.0, -1.0],
            [ 1.0, -1.0,  1.0],
            [ 1.0,  1.0, -1.0],
            [ 1.0,  1.0,  1.0],
            [-1.0,  1.0, -1.0],
            [-1.0,  1.0,  1.0]]

faces = [[0, 1, 3, 2],
         [2, 3, 5, 4],
         [4, 5, 7, 6],
         [6, 7, 1, 0],
         [1, 7, 5, 3],
         [6, 0, 2, 4]]

me = bpy.data.meshes.new("Cube_mesh")
me.verts.extend(vertices)
me.faces.extend(faces)

ob = scene.objects.new(me, "Cube_object")

Blender.Set("curframe", 0)
ob.insertIpoKey(Blender.Object.ROT)

Blender.Set("curframe", 60)
ob.RotX = 2.0 * math.pi
ob.RotY = 2.0 * math.pi
ob.RotZ = 2.0 * math.pi
ob.insertIpoKey(Blender.Object.ROT)

scene.objects.active = ob
