define Package/naiveproxy/description
  NaïveProxy uses Chrome's network stack to camouflage traffic with strong
  censorship resistance and low detectability. Reusing Chrome's stack also
  ensures best practices in performance and security.
endef

define Package/libcronet/description
  Cronet is the Chromium network stack made available to Android apps as a library.

  Cronet takes advantage of multiple technologies that reduce the latency and
  increase the throughput of the network requests that your app needs to work.
