68: 2) STAND-ALONE - you want this machine to run in 'stand-alone' mode and

72: workstations of other LON-CAPA software developers.
73: 4) RUNNING YOUR OWN CLUSTER - this machine is not in the standard LON-CAPA

213: Bad examples are "physics" (too general)
214: or "michiganstateuniversity" (too long)
215: or "msuedu" (internet domain, just make it "msu")
216: or "msuphysics" (only if there is a good reason to limit to department
217: - we don't know of one)
218: or "mydomain" (what is that?)
219: Avoid multiple domains at the same institution, even if it means that you
220: have to actually work together with your colleagues. You can still run
221: multiple library servers within the same domain.
222: If this domain is eventually going to be part of the main production
223: cluster, you MUST contact the LON-CAPA group at MSU (loncapa@loncapa.org)
224: to have a domain name assigned, and then use it exactly as given. This is
225: also true for test installs that might eventually turn into production setups.
