	* Hack 2. Prevent Model-Controller Name Collision, http://net.tutsplus.com/tutorials/php/6-codeigniter-hacks-for-the-masters/

	Instead of:

	```php
	// Filename: Welcome.php
	class Welcome extends Base_Controller {
	    // ...
	    }
	    ```

	    you can write:

	    ```php
	    // Filename: Welcome_controller.php
	    class Welcome_controller extends Base_Controller {
	        // ...
		}
		```

		Thus the class name Welcome is available to be used as a model name instead of those ugly names Welcome_model, Welcome_m, etc.
		The technique of this hack is available, but it is not mandatory.

		How to use this feature:

		Enable the configuration option 'parse_i18n':
		```php
		$config['parse_i18n'] = TRUE;
		```
		Then in your views you can use the following syntax:
		```php
		<i18n>translate_this</i18n>
		```
		or with parameters
		```php
		<i18n replacement="John,McClane">dear</i18n>
		```
		where $lang['dear'] = 'Dear Mr. %s %s,';

		Here is a way how to translate title, alt, placeholder and value attributes:

		```php
		<img src="..." i18n:title="click_me" />
		```
		or with parameters
		```php
		<img src="..." i18n:title="dear|John,McClane" />
		```

		You can override the global setting 'parse_i18n' within the controller by inserting the line:
		```php
		$this->parse_i18n = TRUE; // or FALSE
		```

		Parsing of <i18n> tags is done on the final output buffer only when
		the MIME-type is 'text/html'.

		**Note:** Enabling globally the i18n parser maybe is not the best idea. If you use HMVC, maybe it would
		be better i18n-parsing to be done selectively for particular html-fragments. See below on how to use the
		Parser class for this purpose.

		* KCAPTCHA Version 2.0 - A Port for CodeIgniter, https://github.com/ivantcholakov/codeigniter-kcaptcha
		* Parser class: Driver support has been implemented.

		Instead of:

		```php
		$this->load->library('parser');
		```

		write the following:

		```php
		$this->load->parser();
		```

		Quick tests:

		```php
		// The default parser.
		$this->load->parser();
		echo $this->parser->parse_string('Hello, {name}!', array('name' => 'John'), TRUE);
		```

		There are some other parser-drivers implemented. Examples:

		```php
		// Mustache parser.
		$this->load->parser('mustache');
		echo $this->mustache->parse_string('Hello, {{name}}!', array('name' => 'John'), TRUE);
		```

		```php
		// Parsing a Mustache type of view.
		$email_content = $this->mustache->parse('email.mustache', array('name' => 'John'), TRUE);
		echo $email_content;
		```

		```php
		// Textile parser
		$this->load->parser('textile');
		echo $this->textile->parse_string('h1. Hello!', NULL, TRUE);
		echo $this->textile->parse('hello.textile', NULL, TRUE);
		```

		```php
		// Markdown parser
		$this->load->parser('markdown');
		echo $this->markdown->parse_string('# Hello!', NULL, TRUE);
		echo $this->markdown->parse('hello.markdown', NULL, TRUE);
		```

		```php
		// Markdownify parser
		$this->load->parser('markdownify');
		echo $this->markdownify->parse_string('<h1>Hello!</h1>', NULL, TRUE);
		echo $this->markdownify->parse('hello.html', NULL, TRUE);
		```

		```php
		// LESS parser
		$this->load->parser('less');
		echo $this->less->parse_string('@color: #4D926F; #header { color: @color; } h2 { color: @color; }', NULL, TRUE);
		echo $this->less->parse(DEFAULTFCPATH.'assets/less/lib/bootstrap-3/bootstrap.less', NULL, TRUE);
		```

		Within the folder platform/common/libraries/Parser/drivers/ you may see all the additional parser drivers implemented.
		Also within the folder platform/common/config/ you may find the corresponding configuration files for the drivers,
		name by convention parser_*driver_name*.php. Better don't tweak the default configuration options, you may alter them
		directly on parser call where it is needed.

		The simple CodeIgniter's parser driver-name is 'parser', you may use it according to CodeIgniter's manual.

		**Enanced syntax for using parsers** (which I prefer)

		Using the generic parser class directly, with specifying the desired driver:

		```php
		$this->load->parser();

		// The fourth parameter means Mustache parser that is loaded automatically.
		echo $this->parser->parse_string($mustache_template, $data, true, 'mustache');

		// The fourth parameter means Markdown and auto_link parsers parser to be applied in a chain.
		echo $this->parser->parse_string($content, null, true, array('markdown', 'auto_link'));

		// The same chaining example, this time a configuration option of the second parser has been altered.
		echo $this->parser->parse_string($content, null, true, array('markdown', 'auto_link' => array('attributes' => 'target="_blank"')));
		```

		Using parsers indirectly on rendering views:

		```php
		// You don't need to load explicitly the parser library here.

		// The fourth parameter means that i18n parser is to be applied.
		// This is a way to handle internationalization on views selectively.
		$this->load->view('main_menu_widget', $data, false, 'i18n');
		```

		Using a parser indirectly with Phil Sturgeon's Template library:

		```php
		// You don't need to load explicitly the parser library here.

		$this->template
		    ->set(compact('success', 'messages', 'subject', 'body'))
		        ->enable_parser_body('i18n')  // Not elegant enough, sorry.
			    ->build('email_test');
			    ```

			    * CodeIgniter Checkbox Helper, https://gist.github.com/mikedfunk/4004986
			    * Configured LESS-assets compiler has been added.

			    Have a look at platform/common/config/less_compile.php file. It contains a list of files (sources, destinations)
			    to be used for LESS to CSS compilation. You may edit this list according to your needs. Before compilation, make sure
			    that destination files (if exist) are writable and their containing folders are writable too.

			    LESS-compilation is to be done from command-line. Open a terminal at the folder platform/www/ and write the following
			    command:

			    ```bash
			    php cli.php less compile
			    ```

			    Or, you may choose which LESS-sources to compile by pointing at their names:

			    ```bash
			    php cli.php less compile bootstrap-3 bootstrap-3-min
			    ```

			    * A way for database classes/drivers modification: Files under platform/core/framework/database/ folder may be copied
			    into platform/common/database/ (the prefered location) or platform/applications/{application_name}/database.
			    The copied files can be modified/customized. See file://10.1.0.5/Web Applications/Products/99bazaars/trunkissues/5
