/*
* 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.
