I finished the mt_diff.sh script a while ago and never mentioned it.
It will take two destdir's, go line-by-line through all of the mtree
files, and generate a "package" of sorts which can be applied to
update a netbsd system.

You can find the script here:
http://www.mspo.com/code/mt_diff.sh

My basic conclusion is that the mtree files are not flexible enough to
replace a real packaging system, but they're pretty close.

Would NetBSD rather use the pkgsrc pkg format for the base system, or
would a slightly expanded mtree be preferred?  If it's the latter then
I can give some (now more informed) opinions of what would need to be
done.
