# Every word in DEFAULT_LOCAL_TIDY_CHECKS list has the following format:

#   <local_path_prefix>:,<tidy-check-pattern>

# The tidy-check-patterns of all matching local_path_prefixes will be used.

# For example, external/google* projects will have:

#   ,-google-build-using-namespace,-google-explicit-constructor

#   ,-google-runtime-int,google-runtime-int

# where google-runtime-int is enabled at the end.
