There is no fully automated way right now.
However, you can run `luarocks list --outdated`
to list outdated rocks. Using `--porcelain` for machine-friendly output
something like this can be an automated way to upgrade all rocks:

luarocks list --outdated --porcelain | \
    while read rock cur_version new_version; do \
        luarocks show $rock $new_version >/dev/null 2>&1 || \
            luarocks install $rock $new_version; done

(The `luarocks show` bit checks if an outdated rock on the list
isn't already installed, which may happen if it's a dependency
of another outdated rock that came first in the list.)
