;;; 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.
