-- | the cabal companion
--   
--   <a>vabal</a> finds a version of <a>GHC</a> that is compatible with the
--   constraints imposed on base package found in the cabal file analyzed.
--   It then uses <a>ghcup</a> to obtain the correct version of the
--   compiler (potentially downloading it). It supports two modes:
--   
--   <ul>
--   <li><tt>vabal configure</tt> (it configures your project to use the
--   obtained <a>ghc</a>),</li>
--   <li><tt>vabal</tt> (it prints to stdout options to give to cabal to
--   use the obtained <a>ghc</a>. Options are escaped so that they can sent
--   to the <a>xargs</a> POSIX utility).</li>
--   </ul>
--   
--   See the README for more detailed informations.
