#!/bin/sh
# 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.
# If a newer version of clang-format causes changes to the output that
# are improvements, bump the minimum required version of clang-format
# here, and update manual/contributing.rst. There's a comment there
# that refers to this comment. See also .clang-format.
