/**
 * Command Line Site Reindex
 * Created with stub from jht001 and help from KainX (Thanks to you both)
 * 
 * This script is designed to be called from the command line to allow you
 * to reindex all the liberty content on your site.
 * 
 * cmd_line_reindex takes up to three optional arguments
 * Argument 1 - ContentType
 * 		This is the type of content you wish to reindex using the content type guids
 * 		"pages" will attempt to reindex all content
 * 			Content Type Guids allowed (so far):
 * 			bitarticle, bitblogpost, bitcomment, bitpage, bituser, fisheyegallery, fisheyeimage
 * 
 * Argument 2 - Silent
 * 		Silent = no messages displayed to the console
 * 
 * Argument 3 - UnindexedOnly
 * 		UnindexedOnly = Only index content that isn't already in the index. This function
 * 			is useful for sites that import data from other sites. 
 * 			Note: This function employs sub-selects in the SQL. This will break
 * 				  MySQL 3.x - however works fine on MySQL 4.x, Postgres, Firebird and MSSQL.
 * 
 * Examples:
 * 
 *		php cmd_line_reindex			// reindexes all content on your site with messages
 *		php cmd_line_reindex pages silent unindexedonly // Indexes entire site, no messages - and only content not in the index yet
 *		php cmd_line_reindex bitarticle unindexedonly // Indexes only articles that haven't been indexed yet
 *
 * I have run the "unindexedonly" option several times in a row and was told it attempted to 
 * reindex 20 pieces of content each time. 
 *
 * @package search
