Derived from mel command maya.cmds.attrCompatibility

Example:

import pymel.core as pm

import maya.cmds as cmds

# Rename '.x' attributes in old files to '.tx' for all nodes
# of type 'transform'
#
pm.attrCompatibility( 'transform', 'x', r='tx' )

# Rename the old 'group' node to the new 'transform' node
#
pm.attrCompatibility( 'group', nr='transform' )

# This will cause all subsequent attrCompatibility calls to translate
# files from older versions to version 1.0.
#
pm.attrCompatibility( v='1.0' )
