"ps" definition no longer used?

[Scott Bertilson]

  Just did some grubbing through 8.2.3 source after noticing
the definition.  Seems to only be referenced as a definition
in each Makefile and:
  ndc: ndc.sh Makefile ${.CURDIR}/../Makefile.inc
	sed -e "s|%INDOT%|${INDOT}|" \
	    -e "s|%PS%|${PS}|" \
	    -e "s|%DESTSBIN%|${DESTSBIN}|" \
	    -e "s|%IOT%|${IOT}|" \
	    < ${.CURDIR}/../BIND/named/ndc.sh > ndc

in "/u4/src/bind/8.2.3/src/OLD/BSD/ndc/Makefile".  Can't find
"ndc.sh" anywhere in the distrib, so am guessing this is
cruft.
  Mostly just curiousity because of the output style issues
between the BSD and SysV versions of "ps" that exist on
Solaris.
				Thanks, Scott
