 #
 # To only verify that there are no errors in JSON files, run:
 # $ ./hack/verify-jsonformat.sh
 #
 # Additionally, to verify also the formatting of JSON file, run:
 # $ ./hack/verify-jsonformat.sh --format
 #
 # In case there is a formatting error, you can use this command to fix it
 # automatically:
 # $ ./hack/verify-jsonformat.sh --format --fix
