# Formatting rules are in .clang-format.

# To protect a block of code from automatic formatting, enclose in
# comments such as
#
#  // clang-format off
#  ...
#  // clang-format on

# Sometimes, a comment of the form `// line-break` may appear in the
# code to prevent clang-format from removing an intentional line
# break.

# For emacs users, the file `.dir-locals.el` configures cc-mode for an
# indentation style that is close to but not exactly like what
# clang-format produces. clang-format is authoritative.

# Please see "Code Formatting" in the manual for additional notes.
