# In general, the regular analysis_options.yaml file found at the root of the
# repo also applies to engine code.
#
# This file applies some engine-specific settings to the general rule set.
# Deviations from the general rules are rare. They should be kept to a
# minimum to ensure a unified style across the repo.
#
# The reasoning for deviating from the general style must be documented below.
