Description

Matthiesen Lib

Matthiesen Lib is a lightweight Architectury-style library that enables mod developers to write shared code that works seamlessly across both Fabric and NeoForge mod loaders for Minecraft 1.21.1. Instead of maintaining separate implementations for each platform, you can write your mod logic once in common code and let Matthiesen Lib handle the platform-specific details.

Note: For regular users, This library does nothing on its own - it's a developer tool. If a mod requires Matthiesen Lib, simply drop it in your mods folder alongside the mod that needs it.
