opysA Minecraft installation, described once

Write a short config. Get one file that installs and launches the game on any machine.

Make a pack

Pick a loader, a Java version and your mods in a config file. opys works out every file the game needs and pins each one by hash.

Introduction

One command turns the config into a single file. Host it anywhere. Players get exactly what you built, and updates download only what changed.

The bundle

A small runtime installs a pack and starts the game, with progress and typed errors. It needs nothing else from opys.
