Provision of an X-environment using the HEPiX-X11 scripts

At CERN, we have created a user X11 environment within the HEPiX framework. Customisation is possible at the HEPiX, site, cluster, machine, group and user level, in order of increasing priority. The management of the X11 session is divorced from the window management. FVWM is the default window manager, being light on system resources while providing most of the desired functionality. The assembly of a correctly ordered. fvwmrc is done automatically by the scripts, with customisation allowed at all of the above levels. Two tools are provided to query aspects of that environment. These may be used both at the start of the X-session or when commencing any application. The first is guesskbd, a tool to identify the user's keyboard. A second, provides useful information about a given display.
