It looks like the help output for `hkt findpaths` is working but
not for the other hkt subcommands.

The way you can specify a non-default keyring is with --keyring,
such as

    hkt list --keyring /usr/share/keyrings/debian-role-keys.gpg

At present the only environment variable hkt cares about is HOME.

I'll try to figure out what's going on with the help output.
