+synopsis:            URI manipulation
+description:
+  This package provides facilities for parsing and unparsing URIs, and creating
+  and resolving relative URI references, closely following the URI spec,
+  <http://www.ietf.org/rfc/rfc3986.txt IETF RFC 3986>.
+  .
+  == Backward-compatibility
+  .
+  In @network-2.6@ the "Network.URI" module was split off from the
+  @network@ package into this package. If you're using the "Network.URI"
+  module you can be backward compatible and automatically get it from
+  the right package by using the
+  </package/network-uri-flag network-uri-flag pseudo-package>
+  in your @.cabal@ file's build-depends (along with dependencies for
+  both @network-uri@ and @network@):
+  .
+  >  build-depends:
+  >     network-uri-flag == 0.1.*
+  .
+  Or you can do the same manually by adding this boilerplate to your
+  @.cabal@ file:
+  .
+  > flag network-uri
+  >   description: Get Network.URI from the network-uri package
+  >   default: True
+  >
+  > library
+  >   -- ...
+  >   if flag(network-uri)
+  >     build-depends: network-uri >= 2.6, network >= 2.6
+  >   else
+  >     build-depends: network-uri < 2.6, network < 2.6
+  .
+  That is, get the module from either @network < 2.6@ or from
+  @network-uri >= 2.6@.
