The full style guide is explained in detail on [black's GitHub repository](https://github.com/ambv/black). **There is one exception to this**, however, which is that we set the line length to 99, instead of black's default 88. When using `black` on the command line, simply use it like so: `black -l 99 <src>`.

 You may have noticed we have a `Makefile` and a `make.bat` in the top-level directory. For now, you can do two things with them:
