• Removing dependency on File::Which due to public outburst of flaming
  on cpanra(n)tings by H.Merijn Brand. Try a simple email next time. :(
  
• Embedding an entire copy of File::Which inside the tests instead as
  an alternative to compensating for the lack of build_requires.
  
• Removing the docs directory.
  It only had out of date files and non-free copyrighted materials.
  The tarball was probably illegal to distribute as a result.
