Trivia : Repo is a repository management tool that is built on top of Git. Its main purpose is to help manage projects that consist of many Git repositories, it can also be used to manage uploads to the CMF Gerrit instance and automate aspects of the development workflow.

...

Repo manages this for you by means of an XML based Manifest file. The Manifest file defines which repositories the project uses and links to appropriate revisions of each git repository, i.e where the upstream repositories reside and where they should be cloned locally. It is the manifest.xml (or default.xml) that determines which Git repositories and revisions repo will manage. This manifest.xml file is hosted in a Git repository along with all the other git repositories.

 Credential configuration

Note: it is also recommended to put credentials in .netrc when interacting with the repo.

A sample .netrc file is illustrated below
