# Each desired feature flag state is specified as 'feature-flag=state'.
#
# For example, if the specified files included `config/feature_flags/development/ci_yaml_limit_size.yml` and the desired
# state as specified by the second argument was enabled, the value returned would be `ci_yaml_limit_size=enabled`
