#!/usr/bin/env bash

# Description: Compare the structured output files to the expected output files and exit with an error
#              if they are different. If the environment variable OVERWRITE_FIXTURES is not "false",
#              then this script will instead copy the output files to the expected output directory.
#
# Arguments:
#   - $1: Name of the output folder. This is used to determine the output directory and the expected output directory paths.
#
# Environment Variables:
#   - OVERWRITE_FIXTURES: Controls whether to overwrite fixtures or not. default: "false"
