-<h1>Config Class</h1>
-
-<p>The Config class provides a means to retrieve configuration preferences. These preferences can
-come from the default config file (<samp>application/config/config.php</samp>) or from your own custom config files.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<h2>Anatomy of a Config File</h2>
-
-<p>By default, CodeIgniter has a one primary config file, located at <samp>application/config/config.php</samp>. If you open the file using
-your text editor you'll see that config items are stored in an array called <var>$config</var>.</p>
-
-<p>You can add your own config items to
-this file, or if you prefer to keep your configuration items separate (assuming you even need config items),
-simply create your own file and save it in <dfn>config</dfn> folder.</p>
-
-<p><strong>Note:</strong> If you do create your own config files use the same format as the primary one, storing your items in
-an array called <var>$config</var>. CodeIgniter will intelligently manage these files so there will be no conflict even though
-the array has the same name (assuming an array index is not named the same as another).</p>
-
-<h2>Loading a Config File</h2>
-
-<p><strong>Note:</strong> CodeIgniter automatically loads the primary config file (<samp>application/config/config.php</samp>),
-so you will only need to load a config file if you have created your own.</p>
-
-<p>There are two ways to load a config file:</p>
-
-<ol><li><strong>Manual Loading</strong>
-
-<p>To load one of your custom config files you will use the following function within the <a href="../general/controllers.html">controller</a> that needs it:</p>
-
-<code>$this->config->load('<var>filename</var>');</code>
-
-<p>Where <var>filename</var> is the name of your config file, without the .php file extension.</p>
-
-<p>If you need to load multiple config files normally they will be merged into one master config array. Name collisions can occur, however, if
-you have identically named array indexes in different config files. To avoid collisions you can set the second parameter to <kbd>TRUE</kbd>
-and each config file will be stored in an array index corresponding to the name of the config file. Example:</p>
-
-<code>
-// Stored in an array with this prototype: $this->config['blog_settings'] = $config<br />
-$this->config->load('<var>blog_settings</var>', <kbd>TRUE</kbd>);</code>
-
-<p>Please see the section entitled <dfn>Fetching Config Items</dfn> below to learn how to retrieve config items set this way.</p>
-
-<p>The third parameter allows you to suppress errors in the event that a config file does not exist:</p>
-
-<code>$this->config->load('<var>blog_settings</var>', <dfn>FALSE</dfn>, <kbd>TRUE</kbd>);</code>
-
-</li>
-<li><strong>Auto-loading</strong>
-
-<p>If you find that you need a particular config file globally, you can have it loaded automatically by the system. To do this,
-open the <strong>autoload.php</strong> file, located at <samp>application/config/autoload.php</samp>, and add your config file as
-indicated in the file.</p>
-</li>
-</ol>
-
-
-<h2>Fetching Config Items</h2>
-
-<p>To retrieve an item from your config file, use the following function:</p>
-
-<code>$this->config->item('<var>item name</var>');</code>
-
-<p>Where <var>item name</var> is the $config array index you want to retrieve. For example, to fetch your language choice you'll do this:</p>
-
-<code>$lang = $this->config->item('language');</code>
-
-<p>The function returns FALSE (boolean) if the item you are trying to fetch does not exist.</p>
-
-<p>If you are using the second parameter of the <kbd>$this->config->load</kbd> function in order to assign your config items to a specific index
-you can retrieve it by specifying the index name in the second parameter of the <kbd>$this->config->item()</kbd> function. Example:</p>
-
-<code>
-// Loads a config file named blog_settings.php and assigns it to an index named "blog_settings"<br />
-$this->config->load('<var>blog_settings</var>', <kbd>TRUE</kbd>);<br /><br />
-
-// Retrieve a config item named site_name contained within the blog_settings array<br />
-$site_name = $this->config->item('<dfn>site_name</dfn>', '<var>blog_settings</var>');<br /><br />
-
-// An alternate way to specify the same item:<br />
-$blog_config = $this->config->item('<var>blog_settings</var>');<br />
-$site_name = $blog_config['site_name'];</code>
-
-<h2>Setting a Config Item</h2>
-
-<p>If you would like to dynamically set a config item or change an existing one, you can so using:</p>
-
-<code>$this->config->set_item('<var>item_name</var>', '<var>item_value</var>');</code>
-
-<p>Where <var>item_name</var> is the $config array index you want to change, and <var>item_value</var> is its value.</p>
-
-
-<h2>Helper Functions</h2>
-
-<p>The config class has the following helper functions:</p>
-
-<h2>$this->config->site_url();</h2>
-<p>This function retrieves the URL to your site, along with the "index" value you've specified in the config file.</p>
-
-<h2>$this->config->system_url();</h2>
-<p>This function retrieves the URL to your <dfn>system folder</dfn>.</p>
