The Pronamic Cloudflare plugin adds a number of features, such as WP-CLI commands, to the Cloudflare plugin.
For those who have never heard before WP-CLI, here's a brief description extracted from the official website.
WP-CLI is a set of command-line tools for managing WordPress installations. You can update plugins, set up multisite installs and much more, without using a web browser.
