### Brief System Overview

The top-level scripts and utility scripts should be fairly well-documented. Here
is a brief explanation of how they tie together:

1.  `envs/*` are lists of variables made with bash syntax. A user must set a

        s.identifier_authority = Arrays.copyOf(identAuth, 6);
        s.sub_authority = Arrays.copyOf(subs, subs.length);
        return s;
