If you are not going to do something a lot, it is sometimes faster
to just write a shell script rather than try to figure out exactly
which tools are right for the job.  In this example, the following
would work:

	$ find . -type d | dodir

where dodir is the following shell script:

	#!/bin/sh
	BASE=`pwd`
	while read DIR
	do
		cd $BASE
		cd $DIR
		if [ -r INDEX ]
		then
			mkdir TEMP.$$
			ln *xrefs TEMP.$$
			ln INDEX TEMP.$$
			cd TEMP.$$
			if ls -lt | sed 2q | fgrep INDEX > /dev/null 2>&1
			then
				#
				# Get here if INDEX is newer than
				# all the refs files
				#
			else
				#
				# Get here if some ref files are newer
				# than INDEX
				#
			fi
			cd ..
			rm -rf TEMP.$$
		fi
	done

Ok, I admit it is a kludge, but it works!
