/**
 * _main.php
 * Main markup file (multi-language)

 * MULTI-LANGUAGE NOTE: Please see the README.txt file
 *
 * This file contains all the main markup for the site and outputs the regions 
 * defined in the initialization (_init.php) file. These regions include: 
 * 
 *   $title: The page title/headline 
 *   $content: The markup that appears in the main content/body copy column
 *   $sidebar: The markup that appears in the sidebar column
 * 
 * Of course, you can add as many regions as you like, or choose not to use
 * them at all! This _init.php > [template].php > _main.php scheme is just
 * the methodology we chose to use in this particular site profile, and as you
 * dig deeper, you'll find many others ways to do the same thing. 
 * 
 * This file is automatically appended to all template files as a result of 
 * $config->appendTemplateFile = '_main.php'; in /site/config.php. 
 *
 * In any given template file, if you do not want this main markup file 
 * included, go in your admin to Setup > Templates > [some-template] > and 
 * click on the "Files" tab. Check the box to "Disable automatic append of
 * file _main.php". You would do this if you wanted to echo markup directly 
 * from your template file or if you were using a template file for some other
 * kind of output like an RSS feed or sitemap.xml, for example.
