Thanks for doing this. Couldn't there be a way for the tools in the
base system to participate in alternatives too? (To allow the
default nvi to be overriden by the pksrc vim, or the default rsh by the
rsh from Heimdal, etc.). At least on NetBSD.
Also, mailwrapper could probably be replaced by this mechanism (if it is
provided in the base system).
