-can be found in Homebrew. If you are planning to change some C source here it is
-recommended to use [direnv][] to hook that older version into your shell:
-
-* Install [direnv][] as described in their README
-* Install `clang-format@3.8` with `brew install clang-format@3.8`
-* In byebug source code directory do `echo 'export PATH="/usr/local/opt/clang-format@3.8/bin:$PATH"' > .envrc`
-* Allow direnv to use that `.envrc` file with `direnv allow`
-
-With that your `$PATH` will be updated to use older `clang-format` every time you `cd`
-into byebug source code folder. It will reverted back when you `cd` out of it as well.
