+This folder emulates consuming precompiled modules and components.
+It is compiled separately from the other sources under `src`
+to only generate `*.js` / `*.d.ts` / `*.metadata.json` files,
+but no `*.ngfactory.ts` files.
+
+** WARNING **
+Do not import components/directives from here directly as we want to test that ngc still compiles 
+them when they are not imported.
