  This empty package does not provide any modules; its sole purpose is to
  provide the @network-uri@ Cabal flag logic below so you don't have to include
  that boilerplate in your @.cabal@ file.

  .
  This avoids combining
  @network-uri >= 2.6@ with @network < 2.6@ which both export a
  name-clashing @Network.URI@ module, because
  in network-2.6 the @Network.URI@ module was split off from the
  network package into network-uri-2.6.
  .
  In other words, the logic above makes sure that the @Network.URI@ module
  is provided by either @network-uri@ or by @network@
  (in the <https://en.wikipedia.org/wiki/Exclusive_or XOR> sense).
  .
  In order to benefit from this module, simply include it in your
  @build-depends@ declaration alongside @network@ and @network-uri@.

  /NOTE: It's almost always an error to list this package if network and network-uri aren't both listed as well!/
