-Description: Python Git library - pypy module
- 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.
- .
- This package contains the module built for pypy.
