# It has useful mappings that are normally enabled by default, but there are
# other default mappings that conflict with our builds. The best solution seems
# to be to disable all defaults, import the defaults from the IWYU
# repo and modify the rules that conflict with our build.

# When I saw more than one mapping for these, I typically picked
# what I thought was the "best" one.
