What I miss in teTeX

Hello.
I use teTeX in my Linux machine and the only thing I miss is a command line
interface program that I can run as root and where I can browse installed
and not installed packages, just like in the online catalogue. In this
program I wish to be able to select what extra packages to install or
remove. A command to update the installation would also be great.

I guess this would be possible to build, is anyone doing anything like this?
Or are there problems that I have not thought about?

Gunnar.
