# Use this script to check the system for required tools and process that your app needs.
# A few helper functions are provided to make writing bash a little easier. See the
# script/helpers/function_helpers file for more examples.
#
# A few examples you might use here:
# * 'lucky db.verify_connection' to test postgres can be connected
# * Checking that elasticsearch, redis, or postgres is installed and/or booted
# * Note: Booting additional processes for things like mail, background jobs, etc...
# should go in your Procfile.dev.
