  <h2>APT源转Docker环境变量转换工具</h2>
  
  <h3>工具介绍</h3>
  <p>该工具用于将Debian/Ubuntu系统的APT源地址转换为Docker镜像源部署时所需的环境变量格式。</p>
  
  <h3>使用说明</h3>
  <ol>
    <li>在下方输入框中粘贴您的APT源地址（每行一个deb条目）</li>
    <li>点击"转换"按钮，即可在下方获得转换后的环境变量</li>
    <li>点击"复制结果"按钮复制转换结果</li>
  </ol>
  
  <h3>支持的格式</h3>
  <ul>
    <li>标准APT源：<code>deb https://example.com/debian bookworm main</code></li>
    <li>带架构的APT源：<code>deb [arch=arm64,amd64] https://example.com/debian bookworm main</code></li>
    <li>带目录的APT源：<code>deb https://example.com/debian bookworm main/debian-installer</code></li>
    <li>多组件APT源：<code>deb https://example.com/debian bookworm main contrib non-free</code></li>
  </ul>
