JuK is a music player and a music manager. JuK is, well, at its heart, a jukebox. As is typical with many jukebox applications, JuK allows you to edit the tags of your audio files, and manage your collection and playlists. JuK is part of the KDE Multimedia package. JuK packages are distributed with basically all current Linux and many Unix distributions.
If you'd like to get involved in JuK development, please send patches and whatnot to email@example.com.
General information on developing in and for KDE, including instructions on how to fetch packages from CVS are included in the KDE Developers' Corner.Visit here for Development Information
