/*
 * This utility makes the World from the configuration specified below.
 * It probably won't be much use to anyone outside ZeroTier, Inc. except
 * for testing and experimentation purposes.
 *
 * If you want to make your own World you must edit this file.
 *
 * When run, it expects two files in the current directory:
 *
 * previous.c25519 - key pair to sign this world (key from previous world)
 * current.c25519 - key pair whose public key should be embedded in this world
 *
 * If these files do not exist, they are both created with the same key pair
 * and a self-signed initial World is born.
