 The first build stage is to run doc-gen for all modules separately:
-1. `doc-gen4 single Init Mathlib`
-2. `doc-gen4 single Std Mathlib`
-3. `doc-gen4 single Lean Mathlib`
-4. `doc-gen4 single Mathlib Mathlib`
-We have to pass the `Mathlib` top level module on each invocation here so
-it can generate the navbar on the left hand side properly, it will only
-generate documentation for its first argument module.

-Furthermore one can use the `--ink` flag here to also generate LeanInk
-documentation in addition.

 The second and last stage is the index one which zips up some
