;;; Commentary:
;; I used workgroups2 before this, but workgroups2 had a lot of
;; functionality that I didn't need, and it appears that it is
;; because of this feature creep that workgroups2 will grind Emacs to
;; a halt for long running sessions. I haven't had time to look into
;; why this is the case. Instead I just threw this together.
