+INTRODUCTION					*tabdiff*
+
+Diff many files in multiple tabs.
+
+COMMANDS					*tabdiff-commands*
+
+						*tabdiff-:TabDiff*
+:TabDiff	       
+		Creates a new tab page for each consecutive pair of buffers
+		(split vertically, with the first on the left and the second
+		on the right) and sets all of the windows to diff mode. The
+		original tab page is closed.  
+
+                Intended usage is to start vim with alternating 'old' and
+                'new' files and then invoke this function immediately. It
+                expects there to be only one tab and an even number of
+                buffers, as in: >
+
+	vim -c 'silent :TabDiff'            \
+		/tmp/original/apples apples \
+		/tmp/original/oranges oranges
