....  oh well, aside from that I'm notoriously addicted to "doing
things right" (TM) - and using HLA/CERTI definitely falls into this
category  :-)

###  Works properly:

jive: 22:55:32 ~> billard -n 1 -F/opt/CERTI/share/federations/Test.fed -fTest 
-t 10

New federation: Test
Looking for FOM file...

###  Looks a bit strange, however I'm trying:

jive: 22:49:51 ~> billard -n 1 -F../share/federations/Test.fed -fTest -t 10
[...]
New federation: Test
Looking for FOM file...
   Trying... ../share/federations/Test.fed --> cannot access.
   Now trying.../usr/local/share/federations/../share/federations/Test.fed --> 
cannot access.
   Now trying.../opt/CERTI/share/federations/../share/federations/Test.fed --> 
cannot access.
Next step will fail

###  Both work properly.

Apparently there's no difference at all.
