How to use the vcstool.commands.import_.ImportCommand function in vcstool

clients = [c for c in vcstool_clients if c.type == repo['type']]
        if not clients:
            from vcstool.clients.none import NoneClient

                'returncode': NotImplemented
            }
            jobs.append(job)
            continue

        client = clients[0](path)
        command = ImportCommand(
            args, repo['url'],
            str(repo['version']) if 'version' in repo else None,

        job = {'client': client, 'command': command}
        jobs.append(job)
    return jobs
