Due to several reasons I decided to move the project to GitHub:
https://github.com/conqp/minectl
I first of all uploaded the ready-to-use rpm-files.
I will upload the respective source code as well over the weekend.
I finally decided to move minectl from the hidden place of my website to source forge.
Maybe someone will find it here and consider it a fitting solution for a Minecraft (TM) management software.
