provide an interactive development experience similar to the one you'd get
when programming in Emacs Lisp, Common Lisp (with SLIME or Sly), Scheme (with
Geiser) and Smalltalk.

CIDER is the successor to the now deprecated combination of using SLIME +
swank-clojure for Clojure development.

There are plenty of differences between CIDER and SLIME, but the core ideas
are pretty much the same (and SLIME served as the principle inspiration for
CIDER).")

automatically encrypts messages that you send (e.g., email) when public keys
for all recipients are available, and it protects you from accidentally
sending un-encrypted messages.  It can also be configured to automatically
sign messages that you send.  For details and instructions on how to use
DefaultEncrypt, please refer to the home page or read the comments in the
source file, @file{jl-encrypt.el}.")
