Comment (by rhaas):

 Shorter names for cases 1-5 that are less confusing may be:

 1. MANUAL
 2. BUILD
 3. NATIVE (this is what the old MPI interface used)
 4. AUTOPROBE (this is the same name that IOUtils uses to probe for
 possibly existing checkpoints), or AUTO
 5. SEARCH

 this avoids the confusing name NO_BUILD which is currently used in places
 where NATIVE is meant eg on the Cray machines (if I am not mistaken).
