+;;; Commentary:
+
+;; This provides a player that uses xine. It supports pause and
+;; seeking.
+
+;;; Code:
+
+;; TODO: The video window cannot be disabled. I asked on
+;; gmane.comp.video.xine.user (<87y7ohqcbq.fsf@baldur.tsdh.de>)...
+
+;; TODO: Implement seek-to with "SetPositionX%\n" where X is in {0,10,..,90}
