	/*
	
	http://code.google.com/p/wordpress-mssql/
	
	Contributors: Aizu Ikmal Ahmad & Iwani Khalid
	Requires at least: 2.3.0
	Tested up to: 2.7.1
	Development Status: Alpha
	Database Abstraction Class: ezSQL by Justin Vincent (http://php.justinvincent.com)

	How to install MS-SQL support for Wordpress
	
	1. Download Wordpress ( http://wordpress.org/wordpress-2.7.1-IIS-RC1.zip )
	2. Then, upload it on your webhosting that supports MSSQL and IIS like how you would usually do it
	3. Download our Magic Plugin at ( http://code.google.com/p/wordpress-mssql/ )
	4. Then upload that db.php to your wp-contents folder
	5. Edit the MSSQL database setting in db.php file according to your MSSQL settings 6. You're done :D

	At this moment, this workaround works for these functions, to where we have debugged and tested

	    * Basic submit, edit, manage posts and pages
	    * Comments system
	    * Dynamic sidebar
	    * Changing themes
	    * Installing plugins
	    * Long text retrieval 

	What we didn't have time to debug

	    * Pagination
	    * Categories > Posts retrieval
	    * Dates / Time of posts
	    * Others which we look forward to debug later :D
