-// The ArcClose node specifies a portion of a circle whose center is at (0,0) and whose angles are measured starting at the positive x-axis and sweeping

-// of the circle of which the arc is a portion. The arc extends from the startAngle counterclockwise to the endAngle. The value of radius shall be greater
-// than zero. The values of startAngle and endAngle shall be in the range [-2pi, 2pi] radians (or the equivalent if a different default angle base unit has
-// been specified). If startAngle and endAngle have the same value, a circle is specified and closureType is ignored. If the absolute difference between
-// startAngle and endAngle is greater than or equal to 2pi, a complete circle is produced with no chord or radial line(s) drawn from the center.
-// A closureType of "PIE" connects the end point to the start point by defining two straight line segments first from the end point to the center and then

-// to the start point. Textures are applied individually to each face of the ArcClose2D. On the front (+Z) and back (-Z) faces of the ArcClose2D, when

- \section intro Introduction
-
-  Welcome to the irrXML API documentation.
-  Here you'll find any information you'll need to develop applications with
-  irrXML. If you look for a tutorial on how to start, take a look at the \ref irrxmlexample,
-  at the homepage of irrXML at <A HREF="http://xml.irrlicht3d.org" >xml.irrlicht3d.org</A> 
-  or into the SDK in the directory \example.
- 
-  irrXML is intended to be a high speed and easy-to-use XML Parser for C++, and
-  this documentation is an important part of it. If you have any questions or
-  suggestions, just send a email to the author of the engine, Nikolaus Gebhardt
-  (niko (at) irrlicht3d.org). For more informations about this parser, see \ref history.
-
-  \section features Features
-
-  irrXML provides forward-only, read-only 
-     access to a stream of non validated XML data. It was fully implemented by
-	 Nikolaus Gebhardt. Its current features are:
-
-	 - It it fast as lighting and has very low memory usage. It was 
-	   developed with the intention of being used in 3D games, as it already has been.
-	 - irrXML is very small: It only consists of 60 KB of code and can be added easily
-	   to your existing project.
-	 - Of course, it is platform independent and works with lots of compilers.
-	 - It is able to parse ASCII, UTF-8, UTF-16 and UTF-32 text files, both in 
-	   little and big endian format. 
-	 - Independent of the input file format, the parser can return all strings in ASCII, UTF-8,
-	   UTF-16 and UTF-32 format. 
-	 - With its optional file access abstraction it has the advantage that it can read not
-	   only from files but from any type of data (memory, network, ...). For example when 
-	   used with the Irrlicht Engine, it directly reads from compressed .zip files. 
-	 - Just like the Irrlicht Engine for which it was originally created, it is extremely easy 
-	   to use.
-	 - It has no external dependencies, it does not even need the STL. 
-
-	 Although irrXML has some strenghts, it currently also has the following limitations:
-
-	 - The input xml file is not validated and assumed to be correct. 
-
-    \section irrxmlexample Example
-
-    The following code demonstrates the basic usage of irrXML. A simple xml
-	file like this is parsed:
-    \code
-	<?xml version="1.0"?>
-	<config>
-		<!-- This is a config file for the mesh viewer -->
-		<model file="dwarf.dea" />
-		<messageText caption="Irrlicht Engine Mesh Viewer">
-		Welcome to the Mesh Viewer of the &quot;Irrlicht Engine&quot;.
-		</messageText>
-	</config>
-	\endcode
-
-	The code for parsing this file would look like this:
-	\code
-	#include <irrXML.h>
-	using namespace irr; // irrXML is located in the namespace irr::io
-	using namespace io;
-
-	#include <string> // we use STL strings to store data in this example
-
-	void main()
-	{
-		// create the reader using one of the factory functions
-
-		IrrXMLReader* xml = createIrrXMLReader("config.xml");
-
-		// strings for storing the data we want to get out of the file
-		std::string modelFile;
-		std::string messageText;
-		std::string caption;
-
-		// parse the file until end reached
-
-		while(xml && xml->read())
-		{
-			switch(xml->getNodeType())
-			{
-			case EXN_TEXT:
-				// in this xml file, the only text which occurs is the messageText
-				messageText = xml->getNodeData();
-				break;
-			case EXN_ELEMENT:
-				{
-					if (!strcmp("model", xml->getNodeName()))
-						modelFile = xml->getAttributeValue("file");
-					else
-					if (!strcmp("messageText", xml->getNodeName()))
-						caption = xml->getAttributeValue("caption");
-				}
-				break;
-			}
-		}
-
-		// delete the xml parser after usage
-		delete xml;
-	}
-	\endcode
-
-	\section howto How to use
-
-	Simply add the source files in the /src directory of irrXML to your project. Done.
-
-	\section license License
-
-	The irrXML license is based on the zlib license. Basicly, this means you can do with
-	irrXML whatever you want:

-
-	\section history History
-
-	As lots of references in this documentation and the source show, this xml 
-	parser has originally been a part of the 
-	<A HREF="http://irrlicht.sourceforge.net" >Irrlicht Engine</A>. But because
-	the parser has become very useful with the latest release, people asked for a 
-	separate version of it, to be able to use it in non Irrlicht projects. With
-	irrXML 1.0, this has now been done.

+pugixml 1.9 - an XML processing library
+
+Copyright (C) 2006-2018, by Arseny Kapoulkine ([email protected])
+Report bugs and download new versions at http://pugixml.org/
+
+This is the distribution of pugixml, which is a C++ XML processing library,
+which consists of a DOM-like interface with rich traversal/modification
+capabilities, an extremely fast XML parser which constructs the DOM tree from
+an XML file/buffer, and an XPath 1.0 implementation for complex data-driven
+tree queries. Full Unicode support is also available, with Unicode interface
+variants and conversions between different Unicode encodings (which happen
+automatically during parsing/saving).
+
+The distribution contains the following folders:
+
+	contrib/ - various contributions to pugixml
+
+	docs/ - documentation
+		docs/samples - pugixml usage examples
+		docs/quickstart.html - quick start guide
+		docs/manual.html - complete manual
+
+	scripts/ - project files for IDE/build systems
+
+	src/ - header and source files
+
+	readme.txt - this file.
