From 4d0be4b900c878607600a915a0b7f371b9a557bf Mon Sep 17 00:00:00 2001 From: Michael Olson Date: Sat, 1 Apr 2006 23:31:00 +0000 Subject: Remove emms-tageditor.el, since it only works with emms-pbi.el. It might be useful to re-add this, once it has been rewritten. But first, let's get a release out the door :^) . darcs-hash:20060401233146-1bfb2-a463cb4bfd32568f171ff0ac95edfe1f8757ab91.gz --- emms-tageditor.el | 449 ------------------------------------------------------ 1 file changed, 449 deletions(-) delete mode 100644 emms-tageditor.el diff --git a/emms-tageditor.el b/emms-tageditor.el deleted file mode 100644 index 54832d5..0000000 --- a/emms-tageditor.el +++ /dev/null @@ -1,449 +0,0 @@ -;;; emms-tageditor.el --- Info-editor for EMMS - -;; Copyright (C) 2004, 2005, 2006 Free Software Foundation, Inc. - -;; Author: Ulrik Jensen -;; Keywords: - -;; This file is free software; you can redistribute it and/or modify -;; it under the terms of the GNU General Public License as published by -;; the Free Software Foundation; either version 2, or (at your option) -;; any later version. - -;; This file is distributed in the hope that it will be useful, -;; but WITHOUT ANY WARRANTY; without even the implied warranty of -;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
