Channeleditor is a tool for editing the channels.conf file for the Video Disk Recorder (VDR). It is very intuitive and easy to use. As far as i know there is currently no other tool in portage which provides similar functions. Unfortunately there is currently no versioned source tar-ball for the channeleditor, but i have contacted the author to do so!
Looks like you forgot to attach the ebuild?
