					$this->message('About', 'Using this script', "
					Installing TYPO3 has always been a hot topic on the mailing list and forums. Therefore we've developed this tool which will help you through configuration and testing.
					There are three primary steps for you to take:

					<strong>1: Basic Configuration</strong>
					In this step your PHP-configuration is checked. If there are any settings that will prevent TYPO3 from running correctly you'll get warnings and errors with a description of the problem.
					You'll have to enter a database username, password and hostname. Then you can choose to create a new database or select an existing one.
					Finally the image processing settings are entered and verified and you can choose to let the script update the configuration file, typo3conf/localconf.php with the suggested settings.

					<strong>2: Database Analyser</strong>
					In this step you can either install a new database or update the database from any previous TYPO3 version.
					You can also get an overview of extra/missing fields/tables in the database compared to a raw sql-file.
					The database is also verified agains your 'tables.php' configuration (\$TCA) and you can even see suggestions to entries in \$TCA or new fields in the database.

					<strong>3: Update Wizard</strong>
					Here you will find update methods taking care of changes to the TYPO3 core which are not backwards compatible.
					It is recommended to run this wizard after every update to make sure everything will still work flawlessly.

					<strong>4: Image Processing</strong>
					This step is a visual guide to verify your configuration of the image processing software.
					You'll be presented to a list of images that should all match in pairs. If some irregularity appears, you'll get a warning. Thus you're able to track an error before you'll discover it on your website.

					<strong>5: All Configuration</strong>
					This gives you access to any of the configuration options in the TYPO3_CONF_VARS array. Every option is also presented with a comment explaining what it does.

					<strong>6: typo3temp/</strong>
					Here you can manage the files in typo3temp/ folder in a simple manner. typo3temp/ contains temporary files, which may still be used by the website, but some may not. By searching for files with old access-dates, you can possibly manage to delete unused files rather than files still used. However if you delete a temporary file still in use, it's just regenerated as long as you make sure to clear the cache tables afterwards.
					");

					$this->message('About', 'Why is this script stand-alone?', "
					You would think that this script should rather be a module in the backend and access-controlled to only admin-users from the database. But that's not how it works.
					The reason is, that this script must not be depending on the success of the configuration of TYPO3 and whether or not there is a working database behind. Therefore the script is invoked from the backend init.php file, which allows access if the constant 'TYPO3_enterInstallScript' has been defined and is not false. That is and should be the case <i>only</i> when calling the script 'typo3/install/index.php' - this script!
					");


					$headCode='Header legend';
					$this->message($headCode, 'Just information', '
					This is a simple message with some information about something.
					');
					$this->message($headCode, 'Check was successful', '
					Indicates that something was checked and returned an expected result.
					',-1);
					$this->message($headCode, 'Notice!', '
					Indicates that something is important to be aware of.
					This does <em>not</em> indicate an error.
					',1);
					$this->message($headCode, 'Warning!', '
					Indicates that something may very well cause trouble and you should definitely look into it before proceeding.
					This indicates a <em>potential</em> error.
					',2);
					$this->message($headCode, 'Error!', '
					Indicates that something is definitely wrong and that TYPO3 will most likely not perform as expected if this problem is not solved.
					This indicates an actual error.
