// This function describes how the plugin is used.
//  Make sure and use output buffering
	public static function usage()
	{
		ob_start(); ?>
This plugin returns the total number of days in a given month.
It takes in month and year, if no year is specified, it will
assume it is the current year

Month can take in any of the EE month date formats.
	
	{exp:total_days_in_month month="Feb" year="2016"}
	
	Will output: 29
	
	
This plugin is especially useful when dealing with the solspace plugin calendar:

	{exp:total_days_in_month month='{date format="%m"}' year='{date format="%Y"}'}
	

Or you can also use the current date:

	{exp:total_days_in_month month='{current_time format="%m"}' year='{current_time format="%Y"}'}
