Sorry, but I'm not too sure what you're trying to ask here.
I'm assuming you're talking about the simple template in 2.0.6, since 2.1 didn't come with a simple template. If you're on *nix system, you can use the 'diff' command and do something like:
diff simple simple-original
in the templates directory to get a list of changes between all the files in the directory. Do a diff --help to get a list of options you can use.
