+     "@code{sedsed} can debug, indent, tokenize and HTMLize your sed(1) script.
+
+In debug mode it reads your script and add extra commands to it.  When
+executed you can see the data flow between the commands, revealing all the
+magic sed does on its internal buffers.
+
+In indent mode your script is reformatted with standard spacing.
+
+In tokenize mode you can see the elements of every command you use.
+
+In HTMLize mode your script is converted to a beautiful colored HTML file,
+with all the commands and parameters identified for your viewing pleasure.
+
+With sedsed you can master any sed script.  No more secrets, no more hidden
+buffers.")
