A self-updating SBCL config for propagating the same version of Lisp files across multiple systems

.sbclrc

;; -*-lisp-*-

(ql:quickload :legit)

(defun sync-utils ()
  (let* ((repo (make-instance 'legit:repository
			      :location "/home/wsg/hack/lisp/util-gist/"))
	 (remote "git@gist.github.com:9323a1b03108d4ff10570c26a21425c1.git"))
    (legit:init repo :if-does-not-exist :clone :remote remote)
    (legit:pull repo)
    (load (merge-pathnames #p"util.lisp" (legit:location repo)))))

(sync-utils)

I worked out a simple config file for SBCL that feeds off a GitHub gist. It establishes a directory for that gist's clone, updates it using legit and loads the util.lisp file from there. Obviously, it can easily be extended to load multiple such sources.
