mergemaster should ``just work'' in NetBSD if the tag string is 
changed to NetBSD (although I must admit I haven't tried it yet).  
The only requisite is that the files in /etc actually have Id 
strings.  This was a bit of a pain to update before mergemaster was 
imported into the FreeBSD tree (you have to spend ages finding out if 
you're going to break anything by adding comments to various config 
files - I'm still not convinced the yp file generation stuff is 100% 
when there are comments in /etc/passwd & /etc/group)... :-/
