Announcing http://kumatux.org/ version 1.5, this is a MAJOR upgrade.

kumatux.org is a full system of scripts enabling you to `install' any app just by linking it with symlinks in a special way.

You don't need root privileges to install any app.

Most of all, it doesn't touch the base underlying system, i.e. the system stays COMPLETELY clean, you can have a number of versions of the same app installed at the same time, you can upgrade, downgrade easily, you can run different versions of any app at any time.

It works on any GNU system, I use it to install and run almost 100% of apps on the Nokia N900, as well as my GNU PC.

This is commandline software, so you need to be comfortable working in the CLI, not a beginner.
