This project continues Fabric API #1196, which provides a ModWarn.class that is shrunk as small as possible (<1KB).

This ModWarn.class is highly recommended to be embedded into Loom, with a configuration toggle in remapJar like:

 // If true (default behavior), the mod warn class will be included in // the jar, along with `Main-Class: ModWarn` manifest attribute // (if not present). // // Otherwise, the mod warn class won't be generated, nor the // manifest attribute. generateModClass(true)

We welcome Loom to add this function.

Simply type ./gradlew extractShrunkJar. The output class is in pro-shrunk-output/class/.

NOTE: A pre-compiled class sized 899 bytes is commited already. If you don't trust it, you can regenerate it with the command above, and you'll get one with no difference (unless you modify it).
