Hi Charles, this is my fault for missing the attribution – I'm sorry.
I've just added a credit to you and your repository (see the second sentence).
I had put together this minimal example based on your repository together with a StackOverflow answer containing the build command (https://stackoverflow.com/questions/68476647/errors-with-compiling-zig-to-wasm32-freestanding).
Being just a single file with a simple build command it seemed like a minimal advancement on the state of the art, so I quickly decided to publish, and did not credit the original as I shoud have.
Please let me know if you'd like me to add a particular license to this code in addition to the pointer to your repository, or if you'd like me to take down this example altogether.
