Blender/Python: create a simple export script

Hello, I need a script for Blender 2.49b which must export an object (without animation) into a text file. You can (must) use the attached blend file for testing, I will validate your work when your script works with this model. The exported file must include: -A list of all vertices with position (3 floats) and texture coordinate (2 floats) -A list of all normals (3 floats) -A list of texture names (1 string) -A list of all faces with reference to the vertices (3 ints) -A list of all faces with reference to the textures (1 int) -A list of bones with position (3 floats) and orientation (3 floats) -the bone structure like root(armL(hand(finger1,finger2)),armR(.... -A list for each bone with vertice number / weight (int/float) It's an easy job if you know python and blender because some scripts already does quite the same. Ask me for any question. Thanks
