+ Ldiff: Marking the differences between two LaTeX files
+
+The Ldiff (LaTeX diff) script takes two LaTeX (or LyX) files as input
+and generate a Postscript file that contains the changes between the
+two files: Text that appears in both files is shown in black, text
+that appears only in the first file is shown in red and is crossed
+out, and text that appears only in the second file is shown in blue.
+Note that in some cases, Ldiff will not give correct results.
+
+Ldiff requires python >= 2.0 and dvipost (http://efeu.cybertec.at/).
+
+WARNING: Ldiff might have unwanted effect on the current direcory. It
+might be wise to backup your files before running it.
