Differences from GitPython:

• libvcs.git.GitRepo vs https://gitpython.readthedocs.io/en/3.1.27/reference.html#git.repo.base.Repo.clone

  • libvcs will attempt to match git(1)'s commands flags closely as possible
  • explicit kwargs to make autocompletion easier

• libvcs.git.GitRepo.progress_call is similar to https://gitpython.readthedocs.io/en/3.1.27/reference.html#git.repo.base.Repo.clone's process
