Python script (and module) to clone and update (pull) repositories at a GitHub organization site to local repository directories. Connects to GitHub as the current user. Private repositories can be seen, cloned, and updated if appropriate conditions are met.

• If the environment variable GITUSERTOKEN is given and its value is not blank, authentication is added to the requests for repository information using this value as the personal access token for the current user. If successful, information about both private and public repositories (that the current user can see) will be obtained. If the GITUSERTOKEN environment variable is not given or its value is blank, only information about public repositories will be obtained.

• Uses SSH URLs (i.e., [email protected]/...) to clone the repositories. In order to clone private repositories, the current user's GitHub account must be configured with the user's SSH key.
