                      3:       a LON-CAPA server.  Note that these capabilities
                      4:       describe operating system capabilities (not
                      5:       educational feature capabilities).
                      6: 
                      7:       The idea is that this file becomes a central point
                      8:       for the verification of existing operating system
                      9:       capabilities.

                     14:      automate the handling of software packages on
                     15:      a RedHat linux system.  Due to differing
                     16:      configuration settings, the shaky nature of software

                     22:      pre-installed indestructible palm-pilot-sized units
                     23:      and then there will be no installation problems.

                     25:       Star Trek right now.)
