define Package/meow/description
  A high-performance, rule-based tunneling proxy kernel in Rust,
  compatible with mihomo (Clash Meta). Static binary; configuration lives in
  /etc/meow/config.yaml, service settings in /etc/config/meow.

  Transparent-proxy / gateway mode additionally uses kmod-nft-socket and
  kmod-nft-tproxy.

      help
        Build a smaller binary using the minimal feature bundle (< 8 MiB budget on aarch64)
        instead of the default full feature set.

    config MEOW_EXTERNAL_UI_DOWNLOAD
      bool "Enable external-ui-download feature"
      default y
      help
        Allow meow to auto-download a third-party web dashboard from external-ui-url.

        Optional suffix appended to the version reported by `meow -v` (e.g. -alpha+5d71564).
