## Short script to startup some 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.
|

|
|
## Start up the nodeset
|
|
##
|
|
## $ start_ln 3
|
|
##
|
|
## Let's connect the nodes.
