## Short script to startup two local nodes with
## bitcoind, all running on regtest
## Makes it easier to test things out, by hand.
## Should be called by source since it sets aliases
##
## First load this file up.
##
## $ source contrib/startup_regtest.sh
##
## Start up the nodeset
##
## $ start_ln
##
## Let's connect the nodes.
##
## $ l2-cli getinfo | jq .id
## "02b96b03e42d9126cb5228752c575c628ad09bdb7a138ec5142bbca21e244ddceb"
## $ l2-cli getinfo | jq .binding[0].port
## 9090
## $ l1-cli connect 02b96b03e42d9126cb5228752c575c628ad09bdb7a138ec5142bbca21e244ddceb@localhost:9090

## }
##
## When you're finished, clean up or stop
##
## $ stop_ln # stops the services, keeps the aliases
## $ cleanup_ln # stops and cleans up aliases
##
# Do the Right Thing if we're currently in top of srcdir.
