Tmux automation for setting up an spv wallet

spv.tmux

#!/bin/sh

# Tmux setup for running an spv wallet. This creates two wallets (connected to
# the same master node): one using regular RPC mode with the ticketbuyer and
# voting enabled and a second one with SPV enabled. It receives some coins
# after block 32.
#
# The spv wallet is created in the "spv" dir.
