   Which cluster option would you like to have installed?
   IMPORTANT: to take advantage of the cluster options 1) and 3),
   you must contact lon-capa\@lon-capa.org.
   
   1) PRODUCTION - you want to eventually connect this machine to the
                   LON-CAPA content sharing network. This setting is for
                   schools, colleges, and universities, that currently
                   are running - or in the future will run - courses
   2) STAND-ALONE - you want this machine to run in 'stand-alone' mode and
                    not be connected to other LON-CAPA machines for now
   3) DEVELOPMENT - you want to do software (not content!) development with
                    this workstation and eventually link it with the
                    workstations of other LON-CAPA software developers.
   4) PRESERVE the existing hosts.tab and domain.tab
                   (/home/httpd/lonTabs/hosts.tab and
                    /home/httpd/lonTabs/domain.tab)
