More Control over your TimeMachine Backup
Although Time Machine offers a very slick and intuitive interface to your past data, there can be situations, where you'd rather like a much more common list style approach to the changes off a specific file. Tms, a neat commandline tool from FernLightning does just that. It offers a cvs / svn like interface to your Time Machine data. Among the most interesting features is being able to Diff between two versions, being able to list the difference between two snapshops and listing all unique versions of a file.
The tool as well as the corresponding documentation can be found here.
