13# phosphor-mboxd is a fork of mboxbridge, the reference mbox daemon
14# implementation. mboxbridge is C written with the style of the Linux kernel.
15#
16# phosphor-mboxd extended the reference in C++, and used the OpenBMC C++ style.
17#
18# To remain compliant with the C++ style guide *and* preserve source
19# compatibility with the upstream reference implementation, use two separate
20# styles.
21#
22# Further, clang-format supports describing styles for multiple languages in
23# the one .clang-format file, but *doesn't* make a distinction between C and
24# C++. So we need two files. It gets worse: the -style parameter doesn't take
25# the path to a configuration file as an argument, you instead specify the
26# literal 'file' and it goes looking for a .clang-format or _clang-format file.
27# So now we need to symlink different files in place before calling
28# ${CLANG_FORMAT}. Everything is terrible.
