git can do 95% of what you need: its --find-copies-harder (aka -C -C) logic in the "git log" code finds files with similarities and shows them as such. For example: Create a new repo, put the files in separate commits, use "git log -C -C" to tell you all kinds of similarities. mkdir foo cd foo git init for file in 1 2 3 20; do echo "wow this file sure looks similar to some other file-$file" > file-$file git add file-$file git commit -m "file-$file" done git log -p -C -C The only bit that is missing, if I understand your description correctly, is to find a suitable consensus file. You could try this a few times with different initial files, or choose one that you know is a good one. Hope that helps. Cheers, Ralf
