  * Add lots of new package checks
  Check that Setup.(l)hs exists.
  Check for ./configure file if build-type: Configure
  Check for duplicate modules in library and executables.
  Check ghc-options and cc-options for -I -l -L flags that should be elsewhere
  Check for lots of insane ghc-options that people have used in real packages.
  Check for old ghc -f flags that correspond to extensions

    M ./Distribution/PackageDescription/Check.hs -12 +168
