The installables syntax is not documented in any of the man pages or docbook pages for any of those individual commands. And while these commands really should at least peripherally individually document how installables work, in the meantime we can at least direct people to the right place. This commit also clarifies the unexpected fact that `nix profile remove` and `nix profile upgrade` do *not* take installables. Change-Id: I3b1453cb197a613bbab639c66a466365c3592c6d
