; Cheap and dirty session management for Emacs. 
; Add the location of this file to your load-path,
; Do a (require 'nkv-session) in your .emacs
; Then hit f9 to load up your session files.
; While you work, if you want to remember a file, hit f9 in the buffer. 
; If you want to remember all the current open buffers, you can simply call nkv/session-save-current-buffers
; Whenever you want to save, call nkv/save-session. 
; Or you can add nkv/save-session to kill-emacs-hook to save the session upon quit automatically. 
; Next time, hit f9 to reload your files.
