title: Can't cabal install hunit
body: <p>Very new to the Haskell ecosystem here. I'm trying to install hunit but when I run <code>cabal install hunit</code> I get the following message:</p>
  
  <pre><code>Warning: The install command is a part of the legacy v1 style of cabal usage.
  
  Please switch to using either the new project style and the new-install
  command or the legacy v1-install alias as new-style projects will become the
  default in the next version of cabal-install. Please file a bug if you cannot
  replicate a working v1- use case with the new-style commands.
  
  For more information, see: https://wiki.haskell.org/Cabal/NewBuild
  
  cabal: There is no package named 'hunit'. However, the following package name
  exists: 'HUnit'.
  </code></pre>
