+- Conforms to [google C++ coding style](https://google.github.io/styleguide/cppguide.html) and set 1 tab to 4 spaces.
 - The code appears where it should be. For example the code to support an extra protocol should not be put in general classes like server.cpp, channel.cpp, while a general modification would better not be hidden inside a very specific protocol.
 - Has unittests.
