Well, still admit their existence on the relevant man and Info pages,
E.g. man rm should have a SEE ALSO unlink(1), and via versa.

Also, there must be some words about how they are different.
E.g., on the unlink man page you could at least say "unlink is for
expert uses, normally one should just use rm".
