# This file is meant ONLY as a way to make a hookit hook directly executable.
#
# Normally hookit is bootstrapped via `hookit hook-name "payload"`.
#
# This script allows a ruby executable script to bootstrap hookit and run as
# a hook directly.
#
# Usage:
#
# #!/usr/bin/env ruby
#
# # optionally, set some configuration
# # (if not set, MODULE_ROOT will default to the directory if this script)
#
# $LOG_LEVEL = :error
# $LOGFILE = '/var/log/hookit/hookit.log'
# $MODULE_DIR = "/opt/local/hookit/mod"
#
# # load hookit/setup to bootstrap hookit
# require 'hookit/setup'
#
# execute 'list all the files!' do
#   command 'ls -lah /'
# end
#

# This won't handle every scenario, but essentially it tries to find the
# location of the script that was executed
