-By default, git-xargs will re-attempt opening a pull request that failed due to rate limiting. The `--max-pull-request-retries` flag allows you to specify how many times you'd like a given pull request to be re-attempted in case of failure due to rate limiting. By default, the value is `3`, meaning that if you do not pass this flag, `git-xargs` will retry all rate-limit-blocked pull requests 3 times.

This is useful because the output report will still tell you which repos would have been affected, without actually making changes via the Github API to your remote repositories. Default: `false`. | Boolean | No       |
 | `--draft`                             | Whether to open pull requests in draft mode. Draft pull requests are available for public GitHub repositories and private repositories in GitHub tiered accounts. See [Draft Pull Requests](https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests#draft-pull-requests) for more details.

If you are being rate limited, continue to increase this value until rate limiting eases. Note, this value cannot be negative, so if you pass a value less than 1, the seconds to wait between pull requests will be set to 1 second.

 | `--seconds-to-wait-when-rate-limited` | The number of seconds to pause once git-xargs has detected it has been rate limited. Note that this buffer is in addition to the value of --seconds-between-prs. If you are regularly being rate limited, increase this value until rate limiting eases.
