+	("The Commandline Parser", ["This, in conjunction with the configuration system, is the strongest part of OverCore and the very reason for its continued existence.", "Each configurable option can be assigned to on the command line. Take an option named §Bres-file§/ as an example. To assign to it, you can use §B--§gres-file§/ §msomething§/ (it's case sensitive). That's it, now its value is §msomething§/! Pretty easy, right?", "Now, you're probably thinking: \"I'm not typing that all over again, Martin!\" Well, you don't have to! Options can have their short names. It's a single letter (again, case sensitive) with a plus or minus sign in front of it. So §B--§gres-file§/ §msomething§/ becomes §B+§gf§/ §msomething§/. That's much better, ain't it? And there's more. Short names can be grouped together. If you have a bunch of bool switches, like §B--§garmed§/ (short: §B+§gA§/), §B--no-§gsound§/ (short: §B-§gS§/), §B--no-§gstore§/ (short: §B-§gs§/) and §B--§gforce§/ (short: §B+§gF§/), you can group their shorts into groups with the same boolean value: §B-§gSs§/ §B+§gAF§/. You can even have a non-bool option in a group, it just has to be on the very right (because it needs to be followed by data): §B-§gSs§/ §B+§gAFf§/ §msomething§/. It doesn't matter if that group begins with §B+§/ or §B-§/.", "If you use an option more than once, its last (rightmost) occurence applies. For example, after §B+§gf§/ §msomething§/ §B+§gf§/ §mor_other§/ is parsed, option §Bres-file§/ holds the value §mor_other§/. It goes the same for bools: after §B+§gA§/ §B--no-§garmed§/ §B+§gA§/, §Barmed§/ is §mTrue§/. However, if an option is §cplural§/, all occurences are used. Sequence §B+§gA§/ §B-§gA§/ §B+§gA§/ would be [§mTrue§/, §mFalse§/, §mTrue§/], and §B--§gnum§/ §m1§/ §B--§gnum§/ §m2§/ would end up looking like [§m1§/, §m2§/]. You don't need to type §B--§gnum§/ for every field either: §B--§gnum§/ §m1§/ §m2§/ would work exactly the same. That's because the parser keeps reading everything after a plural option (that takes data, i.e. not bools) right until it encounters two dashes, like those of a following option. You can use just the two dashes to stop the parsing manually, usually when you don't want to follow with a long option. Example: §B--§gnum§/ §m1§/ §m5§/ §m9§/ §B--§/. I repeat: a plural (non-bool) option needs to be terminated by two dashes. This wouldn't work: §B--§gnum§/ §m1§/ §m5§/ §m9§/ §B+§gf§/ §mthat_one§/, everything after §B--§gnum§/ would be consumed as its data, §Bincluding +§gf§/ §mthat_one§/."]),

By default, everything in the config file will be filled with default values and commented out. The general syntax as well as individual options are explained inside. If you run a newer version of the program that offers more configurable options, the config file will be automatically updated. If you'd like to modify an option in the config file, first uncomment it and then change its value.

+		For example option "warp-speed" would be called like so: --warp-speed.
+		Bools take two appearances: --warp-speed is True, while --no-warp-speed is False.

+		#1 Data types.

+		  * "str" - a raw text string, nothing special going on here

+		  * "float" - a float

+		in the config file. Defaults need to have the proper data type, of course, and for
+		plural options they have to be lists.
+		
+		#3 Short names
+		Options can have a short, single letter alias. These are prefixed by a single dash on the command
+		line and don't appear in the config file at all. Again, booleans take special treatment: -a is False,
+		while +a is True.
+		Short names can be grouped: -a -b becomes -ab (both are False), or +a +b becomes +ab (both will be True).
+		If an option requires a parameter (e.g. -f filename), it can still be grouped, it just has to be the
+		rightmost option in the group. Whether the group starts with a + or a - doesn't matter.
+		E.g. -af filename is the same as -a -f filename and +af filename is the same as +a -f filename.
+		
+		#4 Callbacks
+		An option with a callback will invoke it if it appears on the command line (both +a and -a). This is
