Changes made in the v4_6 release of ups (2001-08-26): 

  * ups table file actions extended -- added:
	If( command )
	  ...
	Else()
	  ...
	EndIf( command )
     and
	Unless( command )
	  ...
	Else()
	  ...
	EndUnless( command )
    where the two commands *must* match.  

  * ${UPS_UPS_DIR} is now defined when a ${UPS_PROD_DIR}/ups directory 
    exists, even if is not otherwise declared in the database or command
    line.

  * The list of flavors that will be tried for matching a product has
    been expanded.  Previous to this release, on a Linux+2.4.whatever host
    we would have tried to match flavors:
        Linux+2.4.whatever
 	Linux+2.4
 	Linux+2
 	Linux
	NULL
    The list is now expanded to attempt to guess previous releases:
        Linux+2.4.whatever
 	Linux+2.4
 	Linux+2.4
 	Linux+2.3
 	Linux+2.2
 	Linux+2.1
 	Linux+2.0
 	Linux+2
 	Linux+1
 	Linux+0
 	Linux
	NULL
    Where we simply count down if the last character of a sub-flavor
    is a digit.
