Julian,

There are a couple of new options in -current CTM that may help you:

-B filename	backups whatever would be modified to `filename' before
		applying any patches.

-l 		shows what would be touched

-e regex	specify `include' and `exclude' regexes which you can
-x regex	use to touch parts of the source tree

Something like the following would be helpful

	cd your-source-directory

	for i in somewhere/ctm-files*.gz; do

		ctm -B $i.back -v -v $i		# apply CTM patch

		if [ $? = 0 ]; then # all ok
			rm -f $i.back
		else
			echo "ctm patch $i failed."
			exit 1
		fi

	done


So if you do encounter problems you could 

Run:
	ctm -l ctm-file.gz > list-of-files-that-change

Then:
	ctm -e exp -x exp -e exp ... ctm-file.gz

to selectively update what got missed out.

OR:
	restore from the backup file and re-apply the Ctm patch.

Hope this helps,
Koshy
