;;; Commentary:
;; This package adds pause and seek support for EMMS. While pause and
;; seek are only available for special players.
;; Specically, here we add pause and seek support for
;; `emms-player-mplayer' with mplayer's slave mode enabled. Put
;; something like this to your .emacs first:
;;
;; (setq emms-player-mplayer-command-name "mplayer"
;; emms-player-mplayer-parameters '("-slave")
;; emms-player-list
;; '(emms-player-mplayer
;; emms-player-mplayer-playlist
;; emms-player-mpg321
;; emms-player-ogg123))
;; To use, put this file to your load-path and the following to your
;; .emacs:
;;
;; (require 'emms-player-extensions)
;;; Change Log
;; v 0.21 [2005/07/18 16:42:51] In function `emms-seek', add a call for
;; `emms-lyric-seek' (defined in `emms-lyric.el').
;; v 0.2 [2005/07/17 20:22:53] And `emms-player-paused-p',
;; `emms-player-player-paused-hook', and some modifications to
;; cooperate with another package(`emms-lyric.el'). Rename this
;; file from emms-patch.el to emms-player-extensions.el.
;; v 0.1 The initial version. Add `emms-pause', `emms-seek',
;; `emms-repeat-curr', `emms-unrepeat-curr', `emms-repeat-all',
;; `emms-unrepeat-all'.
;;; Codes:
