synopsis:            Hackage security library
description:         The hackage security library provides both server and
                     client utilities for securing the Hackage package server
                     (<http://hackage.haskell.org/>).  It is based on The Update
                     Framework (<http://theupdateframework.com/>), a set of
                     recommendations developed by security researchers at
                     various universities in the US as well as developers on the
                     Tor project (<https://www.torproject.org/>).
                     .
                     The current implementation supports only index signing,
                     thereby enabling untrusted mirrors. It does not yet provide
                     facilities for author package signing.
                     .
                     The library has two main entry points:
                     "Hackage.Security.Client" is the main entry point for
                     clients (the typical example being @cabal@), and
                     "Hackage.Security.Server" is the main entry point for
                     servers (the typical example being @hackage-server@).

  -- The URI type got split out off the network package after version 2.5, and

  -- However, if we did the same in hackage-security-HTTP, Cabal would consider
  -- those two flag choices (hackage-security:use-network-uri and
  -- hackage-security-HTTP:use-network-uri) to be completely independent; but
  -- they aren't: if it links hackage-security against network-uri and
  -- hackage-security-HTTP against network, we will get type errors when
  -- hackage-security-HTTP tries to pass a URI to hackage-security.
  --
  -- It might seem we can solve this problem by re-exporting the URI type in
  -- hackage-security and avoid the dependency in hackage-security-HTTP
  -- altogether. However, this merely shifts the problem: hackage-security-HTTP
  -- relies on the HTTP library which--surprise!--makes the same choice between
  -- depending on network or network-uri. Cabal will not notice that we cannot
  -- build hackage-security and hackage-security-HTTP against network-uri but
  -- HTTP against network.
  --
  -- We solve the problem by explicitly relying on network-2.6 when choosing
  -- network-uri. This dependency is redundant, strictly speaking. However, it
  -- serves as a proxy for forcing flag choices: since all packages in a
  -- solution must be linked against the same version of network, having one
  -- version of network in one branch of the conditional and another version of
  -- network in the other branch forces the choice to be consistent throughout.
  -- (Note that the HTTP library does the same thing, though in this case the
  -- dependency in network is not redundant.)
