# To update this .clang-format file for a new clang-format version:
# 1. Update the documentation link above.
# 2. Copy the output of `clang-format -dump-config` into a temporary file.
#    a. Comment out all of its lines.
#    b. Uncomment `BasedOnStyle:  LLVM`.
# 3. Compare that temporary file to this .clang-format file.
# 4. Adjust this .clang-format file to record new and updated options.
#    a. Read the new documentation to understand such changes.
# 5. The goal is for the comparison from the temporary file to this .clang-format file to be pure additions (green).
#    a. That is, comments here are recording the defaults, while added lines are our customized settings.
