      Python implementation of the Git file formats and protocols,
      without the need to have git installed.

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

      The project is named after the part of London that Mr. and Mrs. Git live in
      in the particular Monty Python sketch.
