## vcs.GitObjectReader


Read many objects through one `git cat-file --batch` process.


Usage

``` python
vcs.GitObjectReader(
    git_exe,
    cwd,
    git_dir=None,
)
```


Trees and blobs are cached by object id, so walking a long history whose manifests rarely change costs one round-trip per commit plus one per *distinct* manifest - not one process per commit per file.
