+Calendaring Class
+#################
+
+The Calendar class enables you to dynamically create calendars. Your
+calendars can be formatted through the use of a calendar template,
+allowing 100% control over every aspect of its design. In addition, you
+can pass data to your calendar cells.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Calendar class is
+initialized in your controller using the $this->load->library function::
+
+	$this->load->library('calendar');
+
+Once loaded, the Calendar object will be available using::
+
+	$this->calendar
+
+Displaying a Calendar
+=====================
+
+Here is a very simple example showing how you can display a calendar::
+
+	$this->load->library('calendar');
+	echo $this->calendar->generate();
+
+The above code will generate a calendar for the current month/year based
+on your server time. To show a calendar for a specific month and year
+you will pass this information to the calendar generating function::
+
+	$this->load->library('calendar');
+	echo $this->calendar->generate(2006, 6);
+
+The above code will generate a calendar showing the month of June in
+2006. The first parameter specifies the year, the second parameter
+specifies the month.
+
+Passing Data to your Calendar Cells
+===================================
+
+To add data to your calendar cells involves creating an associative
+array in which the keys correspond to the days you wish to populate and
+the array value contains the data. The array is passed to the third
+parameter of the calendar generating function. Consider this example::
+
+	$this->load->library('calendar');
+
+	$data = array(
+	               3  => 'http://example.com/news/article/2006/03/',
+	               7  => 'http://example.com/news/article/2006/07/',
+	               13 => 'http://example.com/news/article/2006/13/',
+	               26 => 'http://example.com/news/article/2006/26/'
+	             );
+
+	echo $this->calendar->generate(2006, 6, $data);
+
+Using the above example, day numbers 3, 7, 13, and 26 will become links
+pointing to the URLs you've provided.
+
+.. note:: By default it is assumed that your array will contain links.
+	In the section that explains the calendar template below you'll see how
+	you can customize how data passed to your cells is handled so you can
+	pass different types of information.
+
+Setting Display Preferences
+===========================
+
+There are seven preferences you can set to control various aspects of
+the calendar. Preferences are set by passing an array of preferences in
+the second parameter of the loading function. Here is an example::
+
+	$prefs = array (
+	               'start_day'    => 'saturday',
+	               'month_type'   => 'long',
+	               'day_type'     => 'short'
+	             );
+
+	$this->load->library('calendar', $prefs);
+
+	echo $this->calendar->generate();
+
+The above code would start the calendar on saturday, use the "long"
+month heading, and the "short" day names. More information regarding
+preferences below.
+
+======================  ===========  ===============================================  ===================================================================
+Preference              Default		Options						Description                                                    
+======================  ===========  ===============================================  ===================================================================
+**template**           	None		None                                         	A string containing your calendar template.
+											See the template section below.
+**local_time**        	time()		None						A Unix timestamp corresponding to the current time.
+**start_day**         	sunday		Any week day (sunday, monday, tuesday, etc.) 	Sets the day of the week the calendar should start on.
+**month_type**        	long          	long, short                                   	Determines what version of the month name to use in the header.
+											long = January, short = Jan.
+**day_type**		abr		long, short, abr 				Determines what version of the weekday names to use in 
+											the column headers. long = Sunday, short = Sun, abr = Su.
+**show_next_prev**	FALSE		TRUE/FALSE (boolean)				Determines whether to display links allowing you to toggle
+											to next/previous months. See information on this feature below.
+**next_prev_url**     	None     	  A URL						Sets the basepath used in the next/previous calendar links.
+======================  ===========  ===============================================  ===================================================================
+
+
+Showing Next/Previous Month Links
+=================================
+
+To allow your calendar to dynamically increment/decrement via the
+next/previous links requires that you set up your calendar code similar
+to this example::
+
+	$prefs = array (
+	               'show_next_prev'  => TRUE,
+	               'next_prev_url'   => 'http://example.com/index.php/calendar/show/'
+	             );
+
+	$this->load->library('calendar', $prefs);
+
+	echo $this->calendar->generate($this->uri->segment(3), $this->uri->segment(4));
+
+You'll notice a few things about the above example:
+
+-  You must set the "show_next_prev" to TRUE.
+-  You must supply the URL to the controller containing your calendar in
+   the "next_prev_url" preference.
+-  You must supply the "year" and "month" to the calendar generating
+   function via the URI segments where they appear (Note: The calendar
+   class automatically adds the year/month to the base URL you
+   provide.).
+
+Creating a Calendar Template
+============================
+
+By creating a calendar template you have 100% control over the design of
+your calendar. Each component of your calendar will be placed within a
+pair of pseudo-variables as shown here::
+
+	$prefs['template'] = '
+
+	   {table_open}<table border="0" cellpadding="0" cellspacing="0">{/table_open}
+
+	   {heading_row_start}<tr>{/heading_row_start}
+
+	   {heading_previous_cell}<th><a href="{previous_url}">&lt;&lt;</a></th>{/heading_previous_cell}
+	   {heading_title_cell}<th colspan="{colspan}">{heading}</th>{/heading_title_cell}
+	   {heading_next_cell}<th><a href="{next_url}">&gt;&gt;</a></th>{/heading_next_cell}
+
+	   {heading_row_end}</tr>{/heading_row_end}
+
+	   {week_row_start}<tr>{/week_row_start}
+	   {week_day_cell}<td>{week_day}</td>{/week_day_cell}
+	   {week_row_end}</tr>{/week_row_end}
+
+	   {cal_row_start}<tr>{/cal_row_start}
+	   {cal_cell_start}<td>{/cal_cell_start}
+
+	   {cal_cell_content}<a href="{content}">{day}</a>{/cal_cell_content}
+	   {cal_cell_content_today}<div class="highlight"><a href="{content}">{day}</a></div>{/cal_cell_content_today}
+
+	   {cal_cell_no_content}{day}{/cal_cell_no_content}
+	   {cal_cell_no_content_today}<div class="highlight">{day}</div>{/cal_cell_no_content_today}
+
+	   {cal_cell_blank}&nbsp;{/cal_cell_blank}
+
+	   {cal_cell_end}</td>{/cal_cell_end}
+	   {cal_row_end}</tr>{/cal_row_end}
+
+	   {table_close}</table>{/table_close}
+	';
+
+	$this->load->library('calendar', $prefs);
+
+	echo $this->calendar->generate();
