-<>
-	This is the event seperator. The text inside the brackets
-	can be anything. But since the text shows up in the property
-	tree it is adviced to give it a meaningfull name like;
-	crank, engine, rumble, gear, squeal, flap, wind, stall or click.
-
-	The value can be defined multiple times, thus anything which is
-	related may have the same name.
-
-  <name>
-	This defines the name of the event. This name is used internally
-	and, although it can me defined multiple times, should have a
-	unique value unless you realy know what you're doing.
-
-	Defining it multiple times could lead to unexpected behaviour.
-	
-  <path>
-	This defined th path to the sound file. The path is relative to the
-	FlightGear root directory but could be specified absolue.
-
-  <property>
-	Define which property triggers the event, and reffers to a node
-	in the FlightGear property tree.
-	 
-	The value is converted to an integer value (anything less than 0.5 is
-	is considered to be 0) and handled if it were a boolean value
-	(0 = false, anything else = true).
-
-	The triger depends on the value of <type>.
-
-  <type>
-	This specifies how the event is triggered.
-	There are multiple options:
-
-	level: 		events are active if the value is true.
-			this is the default behaviour.
-
-	inverted:	events are active if the value is false.
-
-	flipflop:	events are triggered on state changes.
-			this is only usefull for samples which are played
-			once.
-
-  <mode>
-	This defines how the sample should be played:
-
-	once:		the sample is played once.
-			this is the default.
-
-	looped:		the sample plays continuesly,
-			until the event turns false.
-
-  
-  <volume> / <pitch>
-	Defines the following subsection.
-
-    <property>
-	Defins which property supplies the value for the calculation.
-	The value is treatened as a floating point number.
-
-    <type>
-	lin:		lineair handling of the property value.
-			this is the default.
-
-	ln:		convert the property value to a natural logarithmic
-			value before scaling it.
-
-	log:		convert the property value to a true logarithmic
-			value before scaling it.
-
-    <scale>(**)
-	Defines the multiplication factor for the property value.
-	A special condition is when scale is defined as a negative
-	value. In this case the result of |<scale>| * <property) will be
-	subtracted from <default>
-
-    <default>
-	The initial value for this sound. This value is also used as an
-	offset value for calulating the end result.
-
-    <min>
-	Minimum allowed value.
-	This is usefull if sounds start to sound funny. Anything lower
-	will be converted to 0.
-
-    <max>
-
-	Maximum allowed value.
-	This is usefull if sounds gets to loud. Anything higher will be
-	truncated to this value.
-
-
-Calculations are made the following way:
-
-if (scale < 0)
-   value = default - abs(scale) * function(property)
-else
-   value = default + scale * function(property)
-
-where function can be one of {none, log, log10}.
