====== Embed ""YouTube"" Video ======

This is a simple plugin that enables you to embed a [[http://www.youtube.com | YouTube]] video into a wiki page.

===== Usage =====
When you view a video at ""YouTube"" there is a small box to the right of the video titled 'About this video'.  There is a text box labeled **URL** that contains the URL you can use to share the video with others.  NOTE: this plugin uses this URL as it's input - not the URL included in the object/embed tag.

%%
{{youtube url="http://www.youtube.com/watch?v=XXXXXXXXXXX" [width="425" height="350" bgcolor="#ffffff"]}}
%%

	- 'height' is optional.  Defaults to 350 (the standard ""YouTube"" dimensions)
	- 'bgcolor' is optional. Defaults to white (#ffffff)

===== Install =====
Add youtube.php to the actions folder of your Wikka install.
