# phosphor-mboxd is a fork of mboxbridge, the reference mbox daemon
# implementation. mboxbridge is C written with the style of the Linux kernel.
#
# phosphor-mboxd extended the reference in C++, and used the OpenBMC C++ style.
#
# To remain compliant with the C++ style guide *and* preserve source
# compatibility with the upstream reference implementation, use two separate
# styles.
#
# Further, clang-format supports describing styles for multiple languages in
# the one .clang-format file, but *doesn't* make a distinction between C and
# C++. So we need two files. It gets worse: the -style parameter doesn't take
# the path to a configuration file as an argument, you instead specify the
# literal 'file' and it goes looking for a .clang-format or _clang-format file.
# So now we need to symlink different files in place before calling
# ${CLANG_FORMAT}. Everything is terrible.
