define Package/uspot/description
  This package implements a captive portal supporting click-to-continue,
  simple credential-based as well as RADIUS authentication.
  It is UAM capable, and has limited support for RFC5176
  RADIUS Dynamic Authorization Extensions.
  It is meant to be a drop-in replacement for CoovaChilli,
  leveraging the performance and flexibility of the nftables firewall
  without the need for extra kernel modules.
