I did not but such a script would be quite easy.

The permission mapping is maintained in an attribute.
The name of this attribute is derived from the permission
by replacing all non letters/digits by '_', by prefixing with
"_" and suffixing with "_Permission".
You find the details in "AccessControl/PermissionRole.py".
