gplus is a WordPress Plugin.
It provides a WordPress Widget that displays a list of your recent 
Google+ activities in the sidebar. The plugin uses the Google+ API, and 
authenticates via an API key that YOU (the installer) acquire via the 
Google API Console.
Because it uses the public REST API of Google+ that Google documents and 
supports, this plugin is very reliable and simple. (Other WordPress 
widgets that say they show Google+ activity have relied on 
screen-scraping, which makes them brittle and unreliable.)
<h3>Dependencies</h3>
This plugin depends on and uses the published google-api-php-client, 
available at http://code.google.com/p/google-api-php-client/ .
Rather than requires the installer to download this code, it is packaged 
within the plugin. The Google API php client library is licensed 
independently from the gplus WordPress plugin; The former is licensed 
under the Apache 2.0 license.
