A Git library written in Go. This is still in its early development stage, but the packages are roughly organized in this manner:

• core includes types that allow manipulating primitive Git types, such as objects (blobs, trees, commits, tags), refs, symbolic refs, etc.
• config contains types that read, write, and change INI-style config files used by Git.
• format provides types that load, save, and manipulate on-disk metadata formats like index files and pack files.
• util houses useful data structures and convenience types for sophisticated IO-related operations.
• plumbing encompasses low-level functions that can be used to directly manipulate various Git objects within a repository. (e.g. hash-object, cat-file)
• porcelain comprises high-level actions that are assembled from plumbing. (e.g. add, commit, reset)
