The code is original from the author, I just packaged it up!
Here is one way to install it:
(url-copy-file "http://www.wisdomandwonder.com/wordpress/wp-content/uploads/2012/09/hide-comnt-40.tar" "/tmp/hide-comnt-40.tar" t) (require 'package) (package-install-file "/tmp/hide-comnt-40.tar")
Lincoln de Souza reported a fix, remove the quote nil from the package def and Marmalade should accept it, and it did. Here it is.
