define Package/v2raya/description
  v2rayA is a web client for its own Xray-based core. It imports
  subscriptions and share links, selects the fastest node, and provides
  transparent proxy on Linux.

  This package tracks the current upstream 2.5.x release. It installs the
  service together with the matching v2raya_core binary.
