What is the correct way to switch between different "alternatives"? For example, currently my /usr/bin/vi points to nvi. What is the right way to change it to point to vim or elvis? I know how to use 'ln -s' to create/change links, but I suspect that I should really use 'update-alternatives' or some related mechanism. I've read the update-alternatives man page, but didn't understand it--it seems to apply only to package maintainers.
Thanks, Kris
