+Listing [[lst:configure-sly]] configures the [[info:sly#Top][Sly (info)]] Common Lisp IDE for Emacs
+for use with [[http://www.sbcl.org/][Steel Bank Common Lisp (sbcl)]]:
+1. It configures =sly-default-lisp= and =sly-lisp-implementations= as in the
+ ~sly~ documentation string instead of in the [[info:sly#Multiple
+    Lisps][multiple lisps (info)]] manual.
+2. It ensures the [[info:sly#Auto-SLY][automatic connection to the lisp server (info)]] when opening a
+   Common Lisp file.
+3. It configures searching documentation in the [[http://www.lispworks.com/documentation/HyperSpec/Front/][Common Lisp HyperSpec]] according
+   to the [[info:sly#Basic customization][basic customization (info)]] manual.
