git-vendor
==========
A git command for managing vendored dependencies.

`git-vendor` is a wrapper around `git-subtree` commands for checking out and updating vendored dependencies.

By default `git-vendor` conforms to the pattern used for vendoring golang dependencies:

* Dependencies are stored under `vendor/` directory in the repo.
* Dependencies are stored under the fully qualified project path.
    * e.g. `https://github.com/brettlangdon/forge` will be stored under `vendor/github.com/brettlangdon/forge`.

## Usage
See https://brettlangdon.github.io/git-vendor for the current MAN page documentation.

`git-vendor` provides the following commands:

* `git vendor add [--prefix <dir>] <name> <repository> [<ref>]` - add a new vendored dependency.
* `git vendor list [<name>]` - list current vendored dependencies, their source, and current vendored ref.
* `git vendor update <name> [<ref>]` - update a vendored dependency.
* `git vendor upstream <name> [<ref>] [--repo <repository>]` - share with the upstream vendored dependency.

## Installation
Manually:

```bash
git clone https://github.com/brettlangdon/git-vendor
cd ./git-vendor
make
