  * Minor changes to the tar packing code
  Use lazy bytestring when packing tar entry headers rather than strict and
  then making a single chunk lazy bytestring later. The lazy bytestring pack
  will only generate a single chunk for a String that short (<4k).
  Use openBinaryFile rather than openFile + hSetBinaryMode.
  Add a haddock module header with copyright note.
