On the repository all software are given a simple installer for free, and the already installed software can also be removed and updated. This software repository is still in an initial experimental phase and therefore for some system versions it may not be possible to install.
The experimental Debian repository includes selected data reduction/analysis software. The packages are available for a 64 bits Debian based linux system (e.g. Debian, Ubuntu, Mint, etc).
Emmanuel Farhi from the Institute Laue-Langevin (ILL) is the coordinator of this activity. He will keep on updating the repository about twice a year, when the respective LiveDVD is released.
Following this model, interested users can easily setup similar repositories for RedHat or Mac OSX (brew).
