The CERN Computing Rules, as set out in Operational Circular No. 5, demand respect for copyrighted material, including software. CERN provides a large variety of licensed software intended for professional use by CERN contributors. Generally, the licenses are limited to the use of the software at CERN or on CERN hardware. Some software, however, including word processing packages, is available for installation on your home computers as well. Please contact the person at CERN who is responsible for the software in question if you need further details.
