define Package/uanytun/desc-template
uAnytun is a tiny implementation of SATP. Unlike Anytun which is a full
  featured implementation uAnytun has no support for multiple connections
  or synchronisation. It is a small single threaded implementation intended
  to act as a client on small platforms.
