Tmux setup for simnet and 2 parallel nodes with wallets to test reorgs

parallel-nodes.tmux

#!/bin/sh
#
# Script to setup parallel dcrd nodes with separate wallets.
# Useful for testing reorgs by disconnecting nodes, mining individually, then
# reconnecting them.
#
#             alpha  <------>  beta
#    listen   19100           19200
# rpclisten   19101 <.     .> 19201
#           w-alpha  |     | w-beta
# rpclisten   19102           19202
#
# For simplicity, node "beta" is configured to connect to node "alpha" via
# --connect on the command line, so that you can easily disconnect the nodes
# by stopping beta, removing the --connect, then restarting it.
