 More generally, export Bazel build actions into the `compile_commands.json` format that enables great tooling decoupled from Bazel.

 We'll generate a `compile_commands.json` file in the root of the Bazel workspace.
 
-That file describes how Bazel is compiling all the (Objective-)C(++) files. With the compile commands in a common format, build-system-independent tooling (e.g. `clangd` autocomplete, `clang-tidy` linting etc.), can get to work.

 We'll get it running and then move onto the next section while it whirrs away. But in the future, every time you want tooling (like autocomplete) to see new `BUILD`-file changes, rerun the command you chose below! Clangd will automatically pick up the changes.
