	//	The class.gammuWin32 class serves as an API for PHP and Gammu.  Gammu is a free software used for 
	//	managing cellular phones and handheld devices.  The requirement for Gammu is a celluar phone 
	//	and an FBus interface.  I suggest you use Nokia 3310 since the class has been tested using it.  
	//	Gammu can be downloaded from http://www.mwiacek.com/zips/gsm/gammu/gammu_win32.zip  
	//  More information about Gammu can be found at http://www.gammu.net/index.php
	
	//	The following are the features of class.gammuWin32:
		
	//	-	You can implement a php page that could send SMS to single mobile phone (web2mobile)
	//	-	You can extract information from your cellphone such as, message status 
	//	    (read, unsent, sent), folder location (inbox and outbox) and etc.  
	//		Most of all you can extract messages from your cellphone and display it in html format.
		
	//	This is just an introductory version of class.gammuWin32.  A lot of enhancements will 
	//	be done to it as soon as possible.  My goal is to be able to use all the features offered
	//	by Gammu and have it accessed through PHP.
