+			int error_level = error_reporting(), bool is_clone = false)
+		- creates a new xmlArray, which is an simple xml dom parser.
+		- data should be the xml data or an array of, unless is_clone is true.
+		- auto_trim can be used to automatically trim textual data.
+		- error_level specifies whether notices should be generated for
+		  missing elements and attributes.
+		- if is_clone is true, the xmlArray is cloned from another - used
+		  internally only.
+
+	string xmlArray::name()
+		- retrieves the name of the current element, usually ''.
+
+	string xmlArray::fetch(string path, bool get_elements = false)
+		- retrieves the textual value of the specified path.
+		- children are parsed for text, but only textual data is returned
+		  unless get_elements is true.
+
+	xmlArray xmlArray::path(string path, bool return_set = false)
+		- finds any elements that match the path specified.
+		- will always return a set if there is more than one of the element
+		  or return_set is true.
+		- returns in the form of a new xmlArray.
+
+	bool xmlArray::exists(string path)
+		- returns whether the specified path matches at least one element.
+
+	int xmlArray::count(string path)
+		- returns the number of elements the path matches.
+
+	array xmlArray::set(string path)
+		- returns an array of xmlArray's matching the specified path.
+		- this differs from ->path(path, true) in that instead of an xmlArray
+		  of elements, an array of xmlArray's is returned for use with foreach.
+
+	string xmlArray::create_xml(string path = '.')
+		- returns the specified path as an xml file.

+			+ 'size' => Size of column (If applicable) - for example 255 for a large varchar, 10 for an int etc. If not

+			+ 'default' = Default value - do not set if no default required.
+			+ 'null' => Can it be null (true or false) - if not set default will be false.
+			+ 'auto' => Set to true to make it an auto incrementing column. Set to a numerical value to set
+						from what it should begin counting.
+		- Adds indexes as specified within indexes parameter. Each index should be a member of $indexes. Values are:
+			+ 'name' => Index name (If left empty SMF will generate).
+			+ 'type' => Type of index. Choose from 'primary', 'unique' or 'index'. If not set will default to 'index'.

+	does so with the following functions:
+
+	void Display()
+		- loads the posts in a topic up so they can be displayed.
+		- supports wireless, using wap/wap2/imode and the Wireless templates.
+		- uses the main sub template of the Display template.
+		- requires a topic, and can go to the previous or next topic from it.
+		- jumps to the correct post depending on a number/time/IS_MSG passed.
+		- depends on the messages_per_page, defaultMaxMessages and enableAllMessages settings.
+		- is accessed by ?topic=id_topic.START.
+
+	array prepareDisplayContext(bool reset = false)
+		- actually gets and prepares the message context.
+		- starts over from the beginning if reset is set to true, which is
+		  useful for showing an index before or after the posts.
+
+	void Download()
+		- downloads an attachment or avatar, and increments the downloads.
+		- requires the view_attachments permission. (not for avatars!)
+		- disables the session parser, and clears any previous output.
+		- depends on the attachmentUploadDir setting being correct.
+		- is accessed via the query string ?action=dlattach.
+		- views to attachments and avatars do not increase hits and are not
+		  logged in the "Who's Online" log.
+
+	array loadAttachmentContext(int id_msg)
+		- loads an attachment's contextual data including, most importantly,
+		  its size if it is an image.
+		- expects the $attachments array to have been filled with the proper
+		  attachment data, as Display() does.
+		- requires the view_attachments permission to calculate image size.
+		- attempts to keep the "aspect ratio" of the posted image in line,
+		  even if it has to be resized by the max_image_width and
+		  max_image_height settings.
+
+	int approved_attach_sort(array a, array b)
+		- a sort function for putting unapproved attachments first.
+
+	void QuickInTopicModeration()
+		- in-topic quick moderation.

+		- calls show_db_error().
+		- this is used for database connection error handling.
+		- loadavg means this is a load average problem, not a database error.

+	string log_error(string error_message, string error_type = general,
+			string filename = none, int line = none)
+		- logs an error, if error logging is enabled.
+		- depends on the enableErrorLogging setting.
+		- filename and line should be __FILE__ and __LINE__, respectively.
+		- returns the error message. (ie. die(log_error($msg));)
+
+	void fatal_error(string error_message, mixed (bool or string) log = general)
+		- stops execution and displays an error message.
+		- logs the error message if log is missing or true.
+
+	void fatal_lang_error(string error_message_key, mixed (bool or string) log = general,
+			array sprintf = array())
+		- stops execution and displays an error message by key.
+		- uses the string with the error_message_key key.
+		- loads the Errors language file.
+		- applies the sprintf information if specified.
+		- the information is logged if log is true or missing.
+		- logs the error in the forum's default language while displaying the error
+		  message in the user's language
+
+	void error_handler(int error_level, string error_string, string filename,
+			int line)
+		- this is a standard PHP error handler replacement.
+		- dies with fatal_error() if the error_level matches with
+		  error_reporting.
+
+	void setup_fatal_error_context(string error_message)
+		- uses the fatal_error sub template of the Errors template - or the
+		  error sub template in the Wireless template.
+		- used by fatal_error() and fatal_lang_error()
+
+	void show_db_error(bool loadavg = false)
+		- called by db_fatal_error() function
+		- shows a complete page independent of language files or themes.
+		- used only if there's no way to connect to the database or the
+		  load averages are too high to do so.
+		- loadavg means this is a load average problem, not a database error.
