#!/bin/sh
# 本脚本用于管理 openSUSE Tumbleweed ISO 文件。
#
# 主要功能有：
# 1. 下载 DVD/Live ISO 文件、sha256 文件和 asc 证书文件
# 2. 校验新旧 ISO 文件（计算哈希，验证 GPG 签名）
# 3. 更新替换旧版 ISO 文件
#
# 注意：
# 1. 使用前请完整阅读一遍脚本，使用时风险自负。
# 2. 用户需要自行修改需要修改的变量。
# 3. 用户需要自己配置 gpg 工具。

需要注意的一点是，$HOME/Downloads 是 locale 为 en 时下载文件夹的默认位置。所以上面的脚本在更新文件时，不会自动新建 $HOME/Downloads。
