Dpsyco is a automated system to distribute system configurations to several computers. It is written mainly for the Debian distribution but should be portable (without too much difficulties) to other distributions or Unixes as well. It consists of a number of shell scripts to perform the desired actions. With it you can handle users, add ssh-public-keys, patch the system, update things using cfengine, install files (overriding other package files), and more.
tkxinput contains Xi, a library that adds Xinput management capabilities to the Tk toolkit, and a utility named calibrate that can be used to test various aspects of the Xinput configuration of an X server. calibrate can be used, as its name implies, as a touchscreen calibration facility.
