/******************************************************************************

	This code based on example code found at
	http://www.boutell.com/newfaq/creating/include.html, with some
	modifications.  It works with Firefox, Safari, and IE 5+.  So
	saith a notice at the bottom of that page:

		Legal Note: yes, you may use sample HTML, Javascript, PHP and
		other code presented above in your own projects. You may not
		reproduce large portions of the text of the article without

	Modification: Boutell's code requires a div to be inserted before
	calling this function.  This one doesn't.

	Caveat: <style> elements within the include files won't work.
