Extensions to `ring.el'
Extensions to `ring.el'. The code in this library is part of GNU Emacs 23 and later, so this library is useful only for releases prior to Emacs 23. Main new functions here: `ring-convert-sequence-to-ring', `ring-insert+extend', `ring-remove+insert+extend', `ring-member', `ring-next', `ring-previous'. This file should be loaded after loading the standard GNU file `ring.el'. So, in your `~/.emacs' file, do this: (eval-after-load "ring" '(progn (require 'ring+))
