| # Environment variables: | ||
| # - INSTALL_DIRECTORY (optional): defaults to $GOPATH/bin | ||
| # - DEP_RELEASE_TAG (optional): defaults to fetching the latest release | ||
| # | ||
| # You can install using this script: | ||
| # $ curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh | ||
