The diff I choose will be part of a newsreader web application that might become a commercial web application, and I don't want to worry about various licence issues or multiple installs. Currently, my newsreader downloads a newsfeed that includes full articles, and writes over any old versions of the articles that I previously downloaded. I want to change that so an article that has the same ID code as one I already downloaded will be saved as a separate file if it's been updated somehow, and I'll save a diff too, so I can decide myself whether to write over the previous version.
