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
