This is a horribly inefficient script for fetching a tree from a git repository using the GitLab Repositories API. It is only useful if normal git access is somehow broken.
See https://sholland.org/2021/git-clone-piece-by-piece/
Example usage:
$ mkdir my_repo
$ git -C my_repo init
$ python -m gitlab_fetch https://gitlab.example.com/api/v4/projects/12345/repository my_repo
