 * SOURCE CODE LOCATION:

 *   http://code.google.com/p/simple-linkedinphp/
 *    
 * REQUIREMENTS:
 * 
 * 1. You must have cURL installed on the server and available to PHP.
 * 2. You must be running PHP 5+.  
 *  
 * QUICK START:
 * 
 * There are two files needed to enable LinkedIn API functionality from PHP; the
 * stand-alone OAuth library, and the Simple-LinkedIn library. The latest 
 * version of the stand-alone OAuth library can be found on Google Code:
 * 
 *   http://code.google.com/p/oauth/
 * 
 * The latest versions of the Simple-LinkedIn library and this demonstation 
 * script can be found here:
 * 
 *   http://code.google.com/p/simple-linkedinphp/
 *   
 * Install these two files on your server in a location that is accessible to 
 * this demo script. Make sure to change the file permissions such that your 
 * web server can read the files.
 * 
 * Next, make sure the path to the LinkedIn class below is correct.
 * 
 * Finally, read and follow the 'Quick Start' guidelines located in the comments
 * of the Simple-LinkedIn library file.
