;;; Commentary:
;; Based on the perspective.el by Natalie Weizenbaum
;; (http://github.com/nex3/perspective-el) but the perspectives are shared
;; among the frames and could be saved/restored from/to a file.
;;
;; Homepage: https://github.com/Bad-ptr/persp-mode.el
;; Installation:
;; From the MELPA: M-x package-install RET persp-mode RET
;; From a file: M-x package-install-file RET 'path to this file' RET
;; Or put this file into your load-path.
;; Configuration:
;; When installed through the package-install:
;; (with-eval-after-load "persp-mode-autoloads"
;; (setq wg-morph-on nil)
;; ;; switch off the animation of restoring window configuration
;; (setq persp-autokill-buffer-on-remove 'kill-weak)
;; (add-hook 'after-init-hook (lambda () (persp-mode 1))))
;; When installed without generating an autoloads file:
;; (with-eval-after-load "persp-mode"
;; ;; .. all settings you want here
;; (add-hook 'after-init-hook (lambda () (persp-mode 1))))
;; (require 'persp-mode)
;; Dependencies:
;; The ability to save/restore window configurations from/to a file
;; depends on the workgroups.el(https://github.com/tlh/workgroups.el)
;; for the emacs versions < 24.4
;; Customization:
;; M-x: customize-group RET persp-mode RET
;; You can read more in README.md
