Python patch 914575 (https://sourceforge.net/tracker/?func=detail&atid=305470&aid=914575&group_id=5470) adds the ability to generate HTML side by side file differences (full or contextual) to the difflib.py module. This patch has been updated to: 1) simplify the user interface 2) improve the look to use the same color schemes as viewCVS. 3) generate valid XHTML 1.0 Transitional 4) clean up cr/lf issues Any help reviewing this code would be appreciated especially in the area of the user interface, namely the public methods and the passed parameters to __init__. Please use sourceforge to submit comments otherwise respond to this and I will post them for you. Thanks, Dan Gass
