  There were a number of orthogonal problems:
  
  1. The documentation tarball had structure
    
       foo/index.html
       foo/..
  
     which should be
  
       foo-x.y.z-docs/index.html
       foo-x.y.z-docs/..
  
  2. The build client was uploading a .tar.gz file rather than a .tar file,
     but didn't specify the "Content-Encoding: gzip" header
  
  3. The "204 No Content" response by the server was interpreted as an error
     by the client 
  
  With these fixes the build client can build documentation again.
