-MeowLauncher - 一个使用纯 Python 标准库实现的 Minecraft 启动器
-
-功能特性:
-  - 自动获取官方版本清单并下载任意版本
-  - 自动下载游戏依赖库 (libraries) 与原生库 (natives)
-  - 自动下载资源文件 (assets)
-  - 支持离线账号与正版账号 (预留 Yggdrasil 接口)
-  - 跨平台: Windows / Linux / macOS
-  - 零第三方依赖, 仅使用 Python 标准库
-
-用法示例:
-  python3 launcher.py --username Steve --version 1.20.4
-  python3 launcher.py --username Steve --version latest-release --max-mem 4096
-  python3 launcher.py --list-versions
