Easytag is an utility for viewing, editing and writing the id3 tags of different audio files, using a gtk+ interface.
this is a transitional package to easytag. previously, it contained a version of easytag built with mp4/aac support, which is now integrated into the mainline package.
Great for tag editing *.m4v movies made in Handbrake - simply rename *.m4v extension to *.mp4 and edit to your hearts desire. Switch extension back to *.m4v when finished.
