Check in CSS rewriter scripts
This CL adds a set of Python scripts that have been used to help
rewrite CrosAdapta.
Files:
- util.py - Helper functions to make processing/splitting up CSS more easy.
- rewriter.py - Contains a model for rewrites to CSS code as well as
tools for applying rewrites expressed in that model.
- example.py - A set of example rewrites as well as the boiler plate
for running the rewrites from the command line.
