Subject: [PATCH] Add -N (network) option to node.sh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Valid networks are main (mainnet), beta (betanet), pangaea (Pangaea);
default is main.  beta is unsupported yet.

Vary release channel (folder) and bootnodes.

TODO @harmony-ek – support betanet
TODO @harmony-ek – replace hardcoded bootnode with DNS
