Contrib packages aren't loaded by default. You have to modify your
setup a bit so that Emacs knows where to find them and which of them
to load. Generally, you should call slime-setup
with the list
of package-names that you want to use. For example, a setup to load
the slime-scratch
and slime-editing-commands
packages
looks like:
(setq inferior-lisp-program "/opt/sbcl/bin/sbcl") ; your Lisp system (add-to-list 'load-path "~/hacking/lisp/slime/") ; your SLIME directory (require 'slime-autoloads) (slime-setup '(slime-scratch slime-editing-commands))
After starting SLIME, the commands of both packages should be available.
