What is this?

In 2005, Emacs didn't have much advanced features, and it took me more than a decade to continuously improve Emacs.

All the code here is the code that has been tossed, but with the development of the whole community, many plugins have fallen behind and are no longer used.

But I hope to still back up these unused code, I hope some of the code snippets can help other Elisp hackers.

What plugin do I use now?
