## Summary:

  SLIME is the ``Superior Lisp Interaction Mode for Emacs.''

  SLIME extends Emacs with support for interactive programming in
  Common Lisp. The features are centered around slime-mode, an Emacs
  minor-mode that complements the standard lisp-mode. While lisp-mode
  supports editing Lisp source files, slime-mode adds support for
  interacting with a running Common Lisp process for compilation,
  debugging, documentation lookup, and so on.

  The slime-mode programming environment follows the example of
  Emacs's native Emacs Lisp environment. We have also included good
  ideas from similar systems (such as ILISP) and some new ideas of
  our own.

* 2.19 (February 2017)
** Core
*** Function `create-server` now accepts optional `interface` argument.
Swank will bind the PORT on this interface. By default, interface is 127.0.0.1.
This argument can be used, for example, to bind swank on IPv6 interface "::1".
** SBCL backend

*** Completions are now displayed with `completion-at-point'.
The new variable `slime-completion-at-point-functions' should now be
used to customize completion.  The old variable
`slime-complete-symbol-function' still works, but it is considered
obsolete and will be removed eventually.

** SBCL backend
*** M-. can locate forms within PROGN/MACROLET/etc. Needs SBCL 1.2.15
