;; A quick and dirty tree shaker for SBCL. Basically, it destroys the
;; package system and does a gc before saving the lisp image. Gives
;; about a 40% reduction in image size on a basic hello world test.
;; Would like to hear how it works on larger projects.
;;
;; Original idea from: https://groups.google.com/d/msg/comp.lang.lisp/6zpZsWFFW18/WMy4PyA9B4kJ
