;;; core-workgroups.el

;; I use workgroups to accomplish two things:
;;   1. Vim-like tab emulation (type :tabs to see a list of tabs -- maybe I'll add some
;;      code to make a permanent frame header to display these some day)
;;   2. Session persistence (with :ss and :sl)

defuns/defuns-workgroups.el.")

automatically renamed to the project name.")
