Changes made in the v4_5_3 release of ups (2000-10-06): 

Added "ups parent" command, which takes the same options as "ups list".  
Users should note it is rather slow, and stacking multiple
products on one command line saves time, i.e.
	ups parent perl, python
is twice as fast as
	ups parent perl
	ups parent python

Added support for UPS_OVERRIDE environment variable, so you can
set UPS_OVERRIDE to "-H IRIX+6.5.1" (or whatever flavor is
appropriate)  to change ups's mind about the local flavor of
the system.

Added code in setups.{csh,sh} to read ${SETUPS_DIR}/ups_override.${Node}
(where ${Node} is the not-qualified hostname), if it's present, 
 and set the UPS_OVERRIDE variable mentioned above, so that you 
can create that file and globally change ups's mind about the 
default flavors on that system.

Changes to the configure script to deal with read-only clones in AFS                space for $SETUPS_DIR

Table file actions PathPrepend() PathAppend() and PathSet() now are
based on EnvPrepend() EnvAppend() and EnvSet(), which corrects
several bugs fixed in one but not the other.

Fixed a bug causing a core dump if commands were issued with several
optional qualifiers and no mandatory ones.
