highly extensible Git implementation in pure Go

 This package provides a highly extensible git implementation library
 written in pure Go.
 .
 The library does:
  * can be used to manipulate git repositories at low level (plumbing)
    or high level (porcelain), through an idiomatic Go API.
  * supports several types of storage, such as in-memory filesystems, or
    custom implementations using the 'Storer' interface.
  * aims to be fully compatible with git, all the porcelain operations
    are implemented to work exactly as git does.
