# Interesting fact. Bazel `build` command stores cached files in `/private/var/tmp/...` folders
# and when you run build, if it finds cached files, it kind of symlinks the files/folders
# into the `bazel-bin` folder found in the project root. So don't be afraid of re-running builds
# because the files are cached.
