dirdiff

Graphical diff tool

Dirdiff is a graphical tool for displaying the differences between directory trees and for merging changes from one tree into another. Dirdiff can handle up to 5 trees. It displays a main window with a list of the files which are different between the trees, with colored squares to indicate the relative ages of the versions. A menu allows you to display the differences between any two of the versions in another window. Another menu allows you to copy the file from one tree to another.
