 +Name: dulwich
- Description: 
-               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.
