+Description: Pure-python Git library
+ Dulwich is a Python implementation of the file formats and protocols 
+ used by the Git version control system. It can currently read from and write 
+ to existing Git repositories and implements the protocol for pushing and 
+ receiving packs from remote servers.
+ .
+ All functionality is available in pure Python, but for improved performance 
+ replacements of some modules written in C are also available. This package 
+ includes the high performance versions.
