# This script generates a pull request to add the release to operatorhub.io
# Prerequisites:
# - The user has cloned and forked the operator catalog repository
# - The machine running this script has crane installed: https://github.com/google/go-containerregistry/blob/main/cmd/crane/README.md

# Environment variables to tune the script's behavior
# - OPERATORHUB_DIR: The local path to the operator catalog repository.
# - VERSION: The version of the operator to release.
# - HUB_REPO: A regular expression to match the GitHub org/repository of the catalog. Note that this
#   is a regular expression, so special characters need to be escaped.
