+# -*- coding: utf-8 -*-
+"""更新 pac_domains.json：从 v2fly/domain-list-community (geosite) 拉取境外服务
+分类，与现有手工条目合并，生成新的强制走隧道域名后缀表。
+
+用法:
+    python update_pac_domains.py            # 拉取并更新（先自动备份）
+    python update_pac_domains.py --dry-run  # 只统计，不写文件
+
+geosite 数据格式（data/<分类>，每行一条规则）:
+    include:xxx      引用其他分类（递归解析）
+    example.com      匹配域名及其子域（与我们的后缀匹配一致）
+    +example.com     同上（additive）
+    .example.com     仅精确匹配（不匹配子域）-> 跳过
+    -example.com     排除 -> 跳过
+    /regex/          正则 -> 跳过
+    example.com @cn  属性标签 -> 去掉标签
+    无点的单标签（如 chrome）-> 无实际主机名会命中，跳过
