xxdiff, a graphical file comparator and merge tool

xxdiff is a file comparator and merge tool. It is an open-source replacement for Rudy Wortel's xdiff which comes with SGI machines (which was itself inspired by SGI's gdiff). xxdiff can be used to graphically display differences between two (eventually three) files. It can also be used to merge two files together, by allowing the user to select regions and save the results of the selection. It is also an aid in code reviewing, as it allows a reviewer to look at the pieces of changed code and save selected portions of the code to an editor to make comments (horizontal diffs make reviewing much easier, especially for a long list of files).
