MarsSeed [1] filed a deletion request for kamule [2]: This might be considered for removal. Development stopped 6 years ago. Might not work with the current KDE5. Also might not be really needed because it is just a 6 year old GUI frontend for Amule, which has its own GUI based on WxWidgets. Also source is 404 because it is hosted on the problematic linux-apps.com (the closed "OpenDesktop.org" platform), which does not provide direct download links.
