          :param path:
              is the full path to the repo (traditionally ends with /<name>.git)
              or None in which case the repository will be created in the current
              working directory
  
          :param mkdir:
              if specified will create the repository directory if it doesn't
              already exists. Creates the directory with a mode=0755.
              Only effective if a path is explicitly given
  
          :param odbt:
              Object DataBase type - a type which is constructed by providing
              the directory containing the database objects, i.e. .git/objects.
              It will be used to access all object data
  
          :param expand_vars:
              if specified, environment variables will not be escaped. This
              can lead to information disclosure, allowing attackers to
              access the contents of environment variables
  
          :param kwargs:
              keyword arguments serving as additional options to the git-init command
  
          :return: ``git.Repo`` (the newly created repo)
