+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) RUNNING YOUR OWN CLUSTER - this machine is not in the standard LON-CAPA
+                 clusters and won't be in the future and you want the existing
+                 hosts.tab and domain.tab files to be left alone.
+                 (This choice is unlikely what you want to select.)
