+ :TarDiff [filename]
+
+ This command will attempt to show the differences between the tarball
+ version of a file and the associated file on the system. In order to
+ find that file on the system, the script uses the path associated with
+ the file mentioned in the tarball. If the current directory is not
+ correct for that path, :TarDiff will fail to find the associated file.
+
+ If the [filename] is given, that that filename (and path) will be used
+ to specify the associated file.
