Halls, 1. You might do yourself some good coding of your own, if you can -- possibly using a combination of shell/coding. I'd recommend you doing this, assuming you're the one in the right :), because you'll be able to get the custom stats needed for strength in your case, without being limited to someone else's tools. 2. That being said, maybe a few stats would be useful to some people in meld. I wonder if kdiff3 outputs stats. kdiff3 is another GUI diff-merge tool. I use meld and kdiff3. 3. Also, maybe look into the Levenshtein text difference algorithm. In Perl I use Text::Levenshtein (_XS). It provides a character-distance between two texts (ie. how many single-character edits are needed to make one into the other), which then readily translates to a percentage. In that respect, it's more literally-related to the amount of change than line counts.
