Usage

By default this cookbook will attempt to download collectd from collectd.org. If your HTTP request includes Chef as the user agent, collectd.org returns an HTTP response with a message asking you to please stop using their downloads via Chef. It is highly recommended that you override node["collectd"]["url"] with your own download location for collectd.
