Universal UNDO in Python scripts

Cómo programar comando Undo en Python

Implementing a Selective Undo Framework in Python
I've implemented in Python the undo algorithm found in ``Undoing Actions in Collaborative Work: Framework and Experience'' by Prakash and Knister [cite PK94]. Their approach helps structure the objects that make up a ``document''. Those same objects are well suited for use in an embedded language like Python: with them you can write scripts that can be undone! I've implemented standard file operations as a simple concrete example of using the framework.
