# I prefer to have the closing brace of a multi-line declaration or function call on its
# own line. This is unfortunately not yet supported by clang-format. This script is
# a hack to manually introduce my style.
#
# Tracking for this style in clang-format: https://reviews.llvm.org/D33029
#
# Example
# =======
# This is the style I want:
#
# printf(
# "Hello %s %d\n",
# "World",
# 123
# );
