 * Generates Javadoc comments from the class's globalInfo method. Can 
 * automatically update the comments if they're surrounded by

 * 
 
 * Valid options are: 

 * 
 *  -W <classname>
 *  The class to load.
 * 
 *  -nostars
 *  Suppresses the '*' in the Javadoc.
 * 
 *  -dir <dir>
 *  The directory above the package hierarchy of the class.
 * 
 *  -silent
 *  Suppresses printing in the console.
