Doubt regarding mesh files

In the demo simplescenes for the ragdoll creation, mesh named zombie is used.
It contains the following files
zombie_small.mesh
zombie_small.skeleton
zombie.material
zombie.ogreode
zombie_auto.ogreode

the first 3 files are generated when they r exported from maya, but what about the other two files namely the ogreode extension. plz can u explain about these files and how to create them.

you use one of these files at a time. they define how ragdolls move their bodyparts. zombie_auto uses the default values and zombie has some more realistic settings for a human body. its a simple xml format and if you want to create one of your own you have to do it by hand. its really easy to understand, i have done it once.
