-This is a native extension used by the mDNS package (in pkg/mdns) to
-get mDNS support on Mac OS using the C API. When making changes to
-this code the native extension need to be updated namually in the
-package.
-
-When testing changes on Mac OS:
-
-$ ninja -C out/ReleaseX64
-$ src/pkg/mdns/copy_dylib.sh
-
-When the new .dylib file is working upload it to GCS
-
-$ src/pkg/mdns/upload_dylib.sh
-
-The resulting .sha1 file (in pkg/mdns/lib/native) is then updated and
-checked in.
-
-On Linux replace _dylib with _so in the two script names.
-
-The extension is also implemented for Linux, but in a no-operation
-mode with just simple echo testing. The reason for this is that the
-mDNS package can then always load the dynamic library.
