// * CoreFilesystem - Swift module with generated ObjC header
// * FilesystemKit - ObjC module without overlay, has #import <CoreFileystem-Generated.h>

// * CoreDaemon - ObjC module with overlay, the overlay has import DaemonKit
// * DaemonKit - ObjC module without overlay, has #import <CoreDaemon.h>
// * TestDaemon - Swift module, has import CoreDaemon or DaemonKit.

// * CoreMemory - ObjC module with overlay and generated header for overlay, the overlay has import MemoryKit
// * MemoryKit - ObjC module without overlay, has #import <CoreMemory-Generated.h>
