 * <p>The robots.txt protocol is implemented according to the standard specification,
 * supporting pattern matching for user agents, path-based access control, and crawl delay settings.</p>
 *
 * <p>Key features:</p>
 * <ul>
 *   <li>Supports multiple user-agent directives with pattern matching</li>
 *   <li>Handles Allow and Disallow rules for path-based access control</li>

 *
 * <p>This client requires the following initialization parameters:
 * <ul>
 *   <li>endpoint - The URL of the MinIO server</li>
 *   <li>accessKey - The access key for authentication</li>
 *   <li>secretKey - The secret key for authentication</li>
 *   <li>connectTimeout - Connection timeout in milliseconds (default: 10000)</li>
 *   <li>writeTimeout - Write timeout in milliseconds (default: 10000)</li>

When you declare other function parameters that are not part of the path parameters, they are automatically interpreted as "query" parameters.

{* ../../docs_src/query_params/tutorial001.py hl[9] *}

The query is the set of key-value pairs that go after the `?` in a URL, separated by `&` characters.

For example, in the URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...the query parameters are:

During the development, I also contributed to <a href="https://www.starlette.io/" class="external-link" target="_blank">**Starlette**</a>, the other key requirement.
