I'm trying to use this script: http://sourceforge.net/p/ogreaddons/code/HEAD/tree/trunk/blenderimport/ogre_import.py
To import ogre .Mesh files into blender. However when I drop the script into my addons folder it does not show up on the addons list, nor does it's behavior show up in import. If I try and add addon from file, the same thing happens.
Whats going on here? How do I use this addon? If I can't, what other ways can I import an ogre .mesh file?
