php-guzzlehttp-guzzle binary package in Ubuntu Mantic amd64

 Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
 trivial to integrate with web services.
 .
  * Simple interface for building query strings, POST requests, streaming
    large uploads, streaming large downloads, using HTTP cookies, uploading
    JSON data, etc.
  * Can send both synchronous and asynchronous requests using the same
    interface.
  * Uses PSR-7 interfaces for requests, responses, and streams. This
    allows you to utilize other PSR-7 compatible libraries with Guzzle.
  * Supports PSR-18 allowing interoperability between other PSR-18 HTTP Clients.
  * Abstracts away the underlying HTTP transport, allowing you to write
    environment and transport agnostic code; i.e., no hard dependency on cURL,
    PHP streams, sockets, or non-blocking event loops.
  * Middleware system allows you to augment and compose client behavior.
