... and I've been looking at patch(1).  FreeBSD's is currently under GNU 
license, because one of the files (backupfile.c) is.  NetBSD have a 
slightly earlier version of this, covered by the BSD license.  I've yet to 
sit down and compare functionality in depth, but initial testing has shown 
there's little difference in functionality.
