<h3>What does this do?</h3>
<p>This adds a simple Google Map on a page - first a simple image using Google
Static Maps API; and then if the browser supports Javascript, an interactive 
map is added using the Google Maps API v3. No API key is required.</p>

<h3>How do I use it?</h3>
<p>Just insert the tag into your template or page like this:</p>

<code>{gmaps latlng="54.698477,-1.602577"}</code>

<br /><br />

<p>If you want to style your map, like adding a border, padding or whatever, you
must supply the <strong>id</strong> attribute in the tag. For example:</p>

<code>{gmaps latlng="54.698477,-1.602577" id="map-special"}</code>
<br />
<code>#map-special{ padding: 10px; background: #f00; margin: 10px; border: 1px solid #000;}</code>

<h3>What parameters does it take?</h3>
<p> </p>

<ul>		
	<li>
	<em><strong>(required)</strong></em>
	<tt>latlng</tt> - Latitude and longitude for centre of map and marker. 
		Use Google Maps to find this: right-click on location, centre map here, 
		grab the link, find the coordinates.
	</li>
	
	<li>
	<em>(optional)</em>
	<tt>id</tt> - Optional custom DOM ID of the map container.
	</li>

	<li>

	<tt>width</tt> - Width of the map in pixels. Default: 250.
	</li>
	
	<li>

	<tt>height</tt> -  Height of the map in pixels. Default: 250.
	</li>
	
	<li>
	<em>(optional)</em>
	<tt>zoom</tt> - Map zoom level. Default: 12.
	</li>
	
	<li>
	<em>(optional)</em> 
	<tt>maptype</tt> - One of normal, satellite, hybrid, or terrain. Default: normal.
	</li>
	
	<li>
	<em>(optional)</em> 
	<tt>title</tt> - Title of the Point in Info window.
	</li>
