      Simple Python implementation of the Git file formats and
      protocols.

      All functionality is available in pure Python. Optional
      C extensions can be built for improved performance.

      Dulwich takes its name from the area in London where the friendly
      Mr. and Mrs. Git once attended a cocktail party.
