-//
-// 1. It creates a `deapexer` module that actually extracts the files from the `.apex` file and

-// 2. It adds a dependency onto those modules and creates an apex specific variant similar to what

-//    dexpreopt, will work the same way from source and prebuilt.
-//
-// 3. The `deapexer` module adds a dependency from the modules that require the exported files onto

-// It also creates a child module `selector` that is responsible for selecting the appropriate

-// 1. To dedup the selection logic so it only runs in one module.
-// 2. To allow the deapexer to be wired up to a different source for the input apex, e.g. an
