# apt-get install sbcl sbcl-doc
Then I installed slime and several common lisp deb packages. But clfswm deb package does not work. And I found quicklisp provide much more common lisp systems than debian and it is actively maintained. So I decide to use quicklisp for all common lisp systems, only use sbcl deb package.
It is very easy to install quicklisp (from http://www.quicklisp.org/beta/).
$ curl -O http://beta.quicklisp.org/quicklisp.lisp
$ sbcl --load quicklisp.lisp
Then you can use (ql:system-apropos) to search systems and install them with (ql:quickload "xxx"). But quicklisp take too long to initialize, so I put quicklisp initialize code in $HOME/.sbclrc into a function (qlsetup) and call it only when I want to install something with quicklisp. To make systems installed with quicklisp avaiable without quicklisp initialization. I add quicklisp software directory into asdf search path. Create a file named $HOME/.config/common-lisp/source-registry.conf.d/33-quicklisp.conf, its contents is:
(:tree (:home #p"quicklisp/dists/quicklisp/software"))
Then install and configure slime (from https://github.com/quicklisp/quicklisp-slime-helper),
* (qlsetup) * (ql:quickload "quicklisp-slime-helper")
Add the following to $HOME/.emacs
(load (expand-file-name "~/quicklisp/slime-helper.el"))
(setq inferior-lisp-program "sbcl")
Then install hyperspec
# apt-get install hyperspec
