## This script generates a new account keypair, transfers funds to it, and creates
## a bond with those funds.  The amount of can be optionally specified, else a
## default value estimated to be sufficient for about 5000 records.
##
## The `laconic` CLI and a valid config file for it are required.  The default location
## for the config file is `~/.laconic/config.yml`, but this can be controlled with
## the environment variable LACONIC_CONFIG.  A `userKey` for a source account with
## sufficient funds available must be present in this file for the funds transfer
## to succeed.
##
## Example:

## $ scripts/create-and-fund-account.sh 1000000000
