+deno will install the ReScript compiler into a `node_modules/.deno/@[email protected]` directory.
+A direct dependency will be installed into `node_modules/@rescript/webapi`.
+And the runtime (Pervasis) will be installed into `node_modules/.deno/@[email protected]`.
+
+If a package has a namespace (like `@rescript/webapi` has `WebAPI`) it needs to have the `-runtime` argument when creating the `.mlmap` file.
+Because deno installs all these packages in different directories, we need to ensure this still works.
+
+The original sample is based on https://github.com/jderochervlk/rescript-12-beta-deno
