basically, at the end tag, it sets yourVariable = thistag.generatedcontent,
and sets thistag.generatedcontent = ''.
It means by the time you start have to think about the title you've done all
your processing, and can have set variables for the title, meta stuff etc:
eg
<cf_bodycontent name="mystuff">
All your processing, and formatting etc etc
<!-- you can set variables, like the title where ever you like -->
<cfset title = "the result of some processing">
<cfset myKeywords= "keywords and other stuff etc">
</cf_bodycontent>
<!-- at this point _nothing_ has been written to the browser - its all in a
variable called "mystuff".
this will be the first bit of text when you view source in a browser,
except for whitespace -->
<html>
<head>
<title>#title#<title>
<META NAME="Keywords" CONTENT="#myKeywords#">
</head>
<body>
#mystuff#
</body>
</html>
excuse the non JSP code, but you get the idea...?
