+// Command langpackfetch 从官方 Telegram 拉取 langpack(免登公开方法 langpack.getLangPack),
+// 转成 telesrv seed 的 .strings 格式(复数用 Key#one/#other 后缀)。api 凭据用 TDesktop
+// 开源公开的 id/hash。
+//
+// 用法:
+//   langpackfetch languages [pack]                 列出某 pack(默认 android)的可用语言
+//   langpackfetch <out_dir> <langCode> [pack...]   拉取语言包(默认 packs = android ios macos)
