How can I discover all available packages of Emacs?
So far, I was under the impression that I could find almost anything through one of these means:
- The Emacs Manual (
But it does not seem enough. As an example, I came upon
rcirc (an IRC client) online. I could not find it in the above resources. Is it a built-in package? How can I know? Is there a place where all features are listed?
