						<p>
							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.
							<br />
							There are three primary steps for you to take:
						</p>
						<p>
							<strong>1: Basic Configuration</strong>
							<br />
							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.
							<br />
							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.
							<br />
							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.
						</p>
						<p>
							<strong>2: Database Analyser</strong>
							<br />
							In this step you can either install a new database
							or update the database from any previous TYPO3
							version.
							<br />
							You can also get an overview of extra/missing
							fields/tables in the database compared to a raw
							sql-file.
							<br />
							The database is also verified against your
							\'tables.php\' configuration ($TCA) and you can
							even see suggestions to entries in $TCA or new
							fields in the database.
						</p>
						<p>
							<strong>3: Update Wizard</strong>
							<br />
							Here you will find update methods taking care of
							changes to the TYPO3 core which are not backwards
							compatible.
							<br />
							It is recommended to run this wizard after every
							update to make sure everything will still work
							flawlessly.
						</p>
						<p>
							<strong>4: Image Processing</strong>
							<br />
							This step is a visual guide to verify your
							configuration of the image processing software.
							<br />
							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.
						</p>
						<p>
							<strong>5: All Configuration</strong>
							<br />
							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.
						</p>
						<p>
							<strong>6: Cleanup</strong>
							<br />
							Here you can clean up the temporary files in typo3temp/
							folder and the tables used for caching of data in
							your database.
						</p>

					$this->message('About', 'Why is this script stand-alone?', '
						<p>
							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.
							<br />
							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 <em>only</em> when calling the script
							\'typo3/install/index.php\' - this script!
