-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.

 | `--dry-run`                           | If you are in the process of testing out `git-xargs` or your initial set of targeted repos, but you don't want to make any changes via the Github API (pushing your local changes or opening pull requests) you can pass the dry-run flag. 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. Default: `1` second.                                                                                                                 | Integer | No       |

 | `--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.
