  @moduledoc """
  Runs `mix docs`, except with `Zig.Doc.generate_docs/3` as the callback.

  This injects a processing step for zig documentation at the end of the mix
  doc step, including specified zig files as "modules" in the ExDoc system.
  These files are incorporated under the `ZIG CODE` module category.

  This is most effectively used by aliasing it in your mix.exs:

  ```elixir
  def project do
    [
      ...
      aliases: [
        docs: ["zig_doc"]
      ]
      ...
    ]
  end
  ```

  see `Mix.Tasks.Docs` for more information
