explain parsing mechanism, so i dont forget it.

 The Logs Submodule is the core parsing mechanism in Scon.
 It defines classes for opening logfiles from zips, directories, or as a stream, and are intended to be used by higher level apis to adjust to the wanted log retrieval scenario, while keeping the base logic how logs are interpreted unified.
 
+The Parsing Mechanism
+---------------------
+In this example, parsing complete files:
+
+	* Sessions represent a container which hold logfiles from the same directory.
+		-> it has a parse_files method which initiates first pass parsing for the given filenames in the package.
+		-> only 'game.log', 'combat.log' and 'chat.log' are supported for now as session.game_log, session.combat_log and session.chat_log.
+		-> you can only parse one of those files, e.g. first only game log, later combat or chat.
+	* Logfile class directly has 'lines' property holding all the 'lines from the log'. Each kind of logfile has its own subclass in logfiles.
+	* this lines list is converted from a string list to dictionaries, containing log, logtype, and timestamp data in the first parsing.
+	* these dicts are scanned by the class factories and replaced with class based representations of the log packet, coming from their submodule.
+		-> the dict is moved into the dict .values of the created class.
+	* usually at this point, one would discard all dicts, as they represent unknown or unimportant data, what you have left is a list of classes.
+	
+	from here, all lines contain some instance of a class, already telling us, which kind of log this is
+	however to update the rest of the log information, one has to at least call "unpack" once on the instance.
+	having this finetuned in multiple steps however allows us to gain speed by ignoring unwanted information (as combat logs e.g. tend to be large)
+	all other functionality is planend to be in the high level api .game
+	
+	e.g.:
+	for line in game_log.lines:
+		if isinstance(line, Log):
+			if line.unpack():
+				print(line.values.keys())
+	
+	-> unpack can be called several times, as it only unpacks once.
+

 For the programmer, following submodules are of particular interest
