Suggested Commit Messages
You could use this tool to generate a commit message template in a little text box, and optionally copied to the user's clipboard, for example \samples\FileCache\samplesemanticmergetool.bat would generate:
Moved: HashToHex (from FileCache to Hasher)
Changed: Filecache.GetFile, Hasher.HashToHex
Deleted: 3 Using statements
Obviously I would always want my Devs to put in a longer commit about WHY but it would sure make looking at commit histories a little more relaxing.
