<<COMMENT
	Used by Whiteblock for simulated network testing.

	Based upon:
	https://github.com/whiteblock/dockerfiles/blob/a31b412d32d0384de12aa8392e43bac32837b6bc/ethereum/interop-example/launch/start.sh

	Here's an example script used for testing:

	./whiteblock_start.sh \
		--identity=55c7fc76505ddeb6cf750b1f9f43d6d12c1a53b77ada018a390d7592a7f36dbck \
		--peers=/ip4/192.168.0.1/tcp/9000 \
		--validator-keys=/tmp/keygen_10_validators.yaml \
		--gen-state=/tmp/genesis.ssz \
		--port=9008

	The example script was run in the target/release directory of lighthouse.
	The following change was made to this script:

		YAML_KEY_FILE="/tmp/keygen_10_validators.yaml"
