+Arrrgh
+======
+
+Jeff Wofford | July 2014 | e:  biz@jeffwofford.com | w:  http://www.jeffwofford.com
+
+**arrrgh** is a fast, small, simple, powerful, single-header library for parsing command line arguments in C++ using more-or-less POSIX parsing rules. It is written using modern C++11 paradigms so it's safe, fast, and tends to invite clean, small, to-the-point code.
+
+There are lots of other command line parsers out there. Yet every time I wrote a new command line program, I ended up rolling my own underpowered and error-prone argument parsing. I like [TCLAP](http://tclap.sourceforge.net/) but it's a full library with makefiles, lots of source and headers, and the rest. Likewise for getopt, boost, and others: the command line parsing code can end up vastly outweighing the program it's meant to serve. Plus, integrating headers and libraries into C/C++ programs is never a lot of fun, especially when porting to different IDEs and compilers. [The Lean Mean Option Parser](http://optionparser.sourceforge.net/index.html) is nice and small but I didn't prefer its style. You can disagree.
+
+I wrote **arrrgh** to escape the madness. It's a single file. You copy it into your project. You include it. You set up the arguments you want to support. It does the rest.
+
+# To Use
+
+1.	Include the header:
+
+		#include "arrrgh.hpp"
+
+	There's no .lib or .so or .cpp or anything else to muck around with. It's all here.
+
+2.	Create a parser object and give it your program name and description (for the "usage" output):
+
+		arrrgh::parser parser( "<my-prog>", "<description>" );
+
+3.	Add your arguments, templated on the desired type. Example:
+
+		const auto& myArgument = parser.add< float >( ... );
+
+4.	In the add() function you'll indicate the long-form ("--example") and short-form ("-e") switches for this 
+	argument. You can nullify one or the other if you want.
+	You should specify a description (the second argument).
+	You may also specify whether the argument is optional or required, and what the default value is (in case 
+	the user doesn't supply it):
+
+		... parser.add< float >(
+				"<long-form>",			// Use "example" if you want the user to say "--example", 
+										// or leave blank for no long-form.
+				"<description>",		// For "usage" output.
+				'<short-form>', 		// A character. Use '\0' for no short-form.
+				[arrrgh::Optional|arrrgh::Required], // To indicate whether it's required.
+				[default-value] 		// The default value. Defaults to 0 or its equivalent for this type.
+			);
+
+5.	Let 'er rip:
+
+		parser.parse( argc, argv );
+
+	Use try...catch... if you want to catch problems in a healthy way.
+
+6.	Access argument values:
+
+		myArgument.value()		// Returns a float if we templated on <float>.
+
+	try...catch... helps here too because users may give invalid strings for non-string types.
+
+7.	Call parser.show_usage() if you want to print help text.
+
+8.	Do other stuff. See "Example usage" below for "unlabeled" arguments, the "--" marker, and such.

+----------------------------------------------------------------------
+CHANGELOG
+----------------------------------------------------------------------
+
+3.2.0 (2015-11-03)
+
+FEATURES:
+  - OpenDDL-Parser is part of contrib-source.
+  - Experimental OpenGEX-support
+  - CI-check for linux and windows
+  - Coverity check added
+  - New regression testsuite.
+
+FIXES/HOUSEKEEPING:
+  - Hundreds of bugfixes  in all parts of the library
+  - Unified line endings
+
+
+API COMPATIBILITY:
+  - Removed precompiled header to increase build speed for linux
+
+
+3.1.1 (2014-06-15)
+
+FEATURES:
+   - Support for FBX 2013 and newer, binary and ASCII (this is partly
+     work from Google Summer of Code 2012)
+   - Support for OGRE binary mesh and skeleton format
+   - Updated BLEND support for newer Blender versions
+   - Support for arbitrary meta data, used to hold FBX and DAE metadata
+   - OBJ Export now produces smaller files
+   - Meshes can now have names, this is supported by the major importers
+   - Improved IFC geometry generation
+   - M3 support has been removed
+
+FIXES/HOUSEKEEPING:
+    - Hundreds of bugfixes in all parts of the library
+    - CMake is now the primary build system
+
+API COMPATIBILITY:
+    - 3.1.1 is not binary compatible to 3.0 due to aiNode::mMetaData
+      and aiMesh::mName
+    - Export interface has been cleaned up and unified
+    - Other than that no relevant changes
+
+
+3.0 (2012-07-07)
+
+FEATURES:
+   - new export interface similar to the import API.
+   - Supported export formats: Collada, OBJ, PLY and STL
+   - added new import formats: XGL/ZGL, M3 (experimental)
+   - new postprocessing steps: Debone
+   - vastly improved IFC (Industry Foundation Classes) support
+   - introduced API to query importer meta information (such as supported
+       format versions, full name, maintainer info).
+   - reworked Ogre XML import
+   - C-API now supports per-import properties
+
+FIXES/HOUSEKEEPING:
+
+   - hundreds of bugfixes in all parts of the library
+   - unified naming and cleanup of public headers
+   - improved CMake build system
+   - templatized math library
+   - reduce dependency on boost.thread, only remaining spot
+     is synchronization for the C logging API
+
+API COMPATIBILITY:
+   - renamed headers, export interface, C API properties and meta data
+     prevent compatibility with code written for 2.0, but in
+     most cases these can be easily resolved
+   - Note: 3.0 is not binary compatible with 2.0
+
+
+
+
+2.0 (2010-11-21)
+
+FEATURES:
+   - Add support for static Blender (*.blend) scenes
+   - Add support for Q3BSP scenes
+   - Add a windows-based OpenGL sample featuring texturing & basic materials
+   - Add an experimental progress feedback interface.
+   - Vastly improved performance (up to 500%, depending on mesh size and
+     spatial structure) in some expensive postprocessing steps
+   - AssimpView now uses a reworked layout which leaves more space
+     to the scene hierarchy window
+
+   - Add C# bindings ('Assimp.NET')
+   - Keep BSD-licensed and otherwise free test files in separate
+     folders (./test/models and ./test/models-nonbsd).
+
+FIXES:
+   - Many Collada bugfixes, improve fault tolerance
+   - Fix possible crashes in the Obj loader
+   - Improve the Ogre XML loader
+   - OpenGL-sample now works with MinGW
+   - Fix Importer::FindLoader failing on uppercase file extensions
+   - Fix flawed path handling when locating external files
+   - Limit the maximum number of vertices, faces, face indices and
+     weights that Assimp is able to handle. This is to avoid
+     crashes due to overflowing counters.
+
+   - Updated XCode project files
+   - Further CMAKE build improvements
+
+
+API CHANGES:
+   - Add data structures for vertex-based animations (These are not
+     currently used, however ...)
+   - Some Assimp::Importer methods are const now.
+
+
+
+
+
+1.1 (2010-04-17)
+This is the list of relevant changes from the 1.0 (r412) release to 1.1 (r700).
+
+FEATURES:
+  - Vastly improved Collada support
+  - Add MS3D (Milkshape 3D) support
+  - Add support for Ogre XML static meshes
+  - Add experimental COB (TrueSpace) support
+  - Automatic test suite to quickly locate regressions
+  - D bindings (`dAssimp`)
+  - Python 2.n bindings (`PyAssimp`)
+  - Add basic support for Unicode input files (utf8, utf16 and utf32)
+  - Add further utilities to the `assimp` tool (xml/binary dumps, quick file stats)
+  - Switch to a CMAKE-based build system including an install target for unix'es
+  - Automatic evaluation of subdivision surfaces for some formats.
+  - Add `Importer::ReadFileFromMemory` and the corresponding C-API `aiReadFileFromMemory`
+  - Expose further math utilities via the C-API (i.e. `aiMultiplyMatrix4`)
+
+  - Move noboost files away from the public include directory
+  - Many, many bugfixes and improvements in existing loaders and postprocessing steps
+  - Documentation improved and clarified in many places.
+  - Add a sample on using Assimp in conjunction with OpenGL
+
+  - Distribution/packaging: comfortable SDK installer for Windows
+  - Distribution/packaging: improved release packages for other architectures
+
+CRITICAL FIXES:
+  - Resolve problems with clashing heap managers, STL ABIs and runtime libraries (win32)
+  - Fix automatic detection of file type if no file extension is given
+  - Improved exception safety and robustness, prevent leaking of exceptions through the C interface
+  - Fix possible heap corruption due to material properties pulled in incorrectly
+  - Avoid leaking in certain error scenarios
+  - Fix 64 bit compatibility problems in some loaders (i.e. MDL)
+
+BREAKING API CHANGES:
+  - None -
+
+MINOR API BEHAVIOUR CHANGES:
+ - Change quaternion orientation to suit to the more common convention (-w).
+ - aiString is utf8 now. Not yet consistent, however.

+Open Asset Import Library (assimp)
+==================================
+
+APIs are provided for C and C++. There are various bindings to other languages (C#, Java, Python, Delphi, D). Assimp also runs on Android and iOS.
+
+Additionally, assimp features various __mesh post processing tools__: normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials and many more.
+
+This is the development trunk containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from [assimp.sf.net](http://assimp.sf.net) or from *nix package repositories.
+The current build status is:
+
+Linux [![Linux Build Status](https://travis-ci.org/assimp/assimp.png)](https://travis-ci.org/assimp/assimp)

+### Building ###
+Take a look into the `INSTALL` file. Our build system is CMake, if you used CMake before there is a good chance you know what to do.
+
+### Ports ###
+* [Android](port/AndroidJNI/README.md)
+* [Python](port/PyAssimp/README.md)
+* [.NET](port/AssimpNET/Readme.md)
+* [Pascal](port/AssimpPascal/Readme.md)
+
+#### Repository structure ####
+Open Asset Import Library is implemented in C++. The directory structure is:
+
+	/code		Source code
+	/contrib	Third-party libraries
+	/doc		Documentation (doxysource and pre-compiled docs)
+	/include	Public header C and C++ header files
+	/scripts 	Scripts used to generate the loading code for some formats
+	/port		Ports to other languages and scripts to maintain those.
+	/test		Unit- and regression tests, test suite of models
+	/tools		Tools (old assimp viewer, command line `assimp`)
+	/samples	A small number of samples to illustrate possible
+                        use cases for Assimp
+	/workspaces	Build environments for vc,xcode,... (deprecated,
+			CMake has superseeded all legacy build options!)
+
+
+### Where to get help ###
+For more information, visit [our website](http://assimp.sourceforge.net/). Or check out the `./doc`- folder, which contains the official documentation in HTML format.
+(CHMs for Windows are included in some release packages and should be located right here in the root folder).
+
+If the docs don't solve your problem, ask on [StackOverflow](http://stackoverflow.com/questions/tagged/assimp?sort=newest). If you think you found a bug, please open an issue on Github.
+
+For development discussions, there is also a (very low-volume) mailing list, _assimp-discussions_
+  [(subscribe here)]( https://lists.sourceforge.net/lists/listinfo/assimp-discussions)
+
+Open Asset Import Library is a library to load various 3d file formats into a shared, in-memory format. It supports more than __40 file formats__ for import and a growing selection of file formats for export.
+
+And we also have an IRC-channel at freenode: #assetimporterlib . You can easily join us via: [KiwiIRC/freenote](https://kiwiirc.com/client/irc.freenode.net), choose your nickname and type
+> /join #assetimporterlib
+
+### Contributing ###
+Contributions to assimp are highly appreciated. The easiest way to get involved is to submit
+a pull request with your changes against the main repository's `master` branch.
+
+### Donate ###
+If you like assimp, consider buying us a beer (or two):
+[Donate](http://sourceforge.net/donate/index.php?group_id=226462)
+
+### License ###
+Our license is based on the modified, __3-clause BSD__-License.
+
+An _informal_ summary is: do whatever you want, but include Assimp's license text with your product -
+and don't sue us if our code doesn't work. Note that, unlike LGPLed code, you may link statically to Assimp.
+For the legal details, see the `LICENSE` file.
+
+### Why this name ###
+Sorry, we're germans :-), no english native speakers ...

+// Stuff that is not used by Assimp is commented.
+
+
+// NOTE
+// this file serves as input data to the `./scripts/genblenddna.py`
+// script. This script generates the actual binding code to read a
+// blender file with a possibly different DNA into our structures.
+// Only `struct` declarations are considered and the following
+// rules must be obeyed in order for the script to work properly:
+//
+// * C++ style comments only
+//
+// * Structures may include the primitive types char, int, short,
+//   float, double. Signedness specifiers are not allowed on
+//   integers. Enum types are allowed, but they must have been
+//   defined in this header.
+//
+// * Structures may aggregate other structures, unless not defined
+//   in this header.
+//
+// * Pointers to other structures or primitive types are allowed.
+//   No references or double pointers or arrays of pointers.
+//   A pointer to a T is normally written as std::shared_ptr, while a
+//   pointer to an array of elements is written as boost::
+//   shared_array. To avoid cyclic pointers, use raw pointers in
+//   one direction.
+//
+// * Arrays can have maximally two-dimensions. Any non-pointer
+//   type can form them.
+//
+// * Multiple fields can be declare in a single line (i.e `int a,b;`)
+//   provided they are neither pointers nor arrays.
+//
+// * One of WARN, FAIL can be appended to the declaration (
+//   prior to the semiolon to specifiy the error handling policy if
+//   this field is missing in the input DNA). If none of those
+//   is specified the default policy is to subtitute a default
+//   value for the field.
+//
+
+#define WARN // warn if field is missing, substitute default value
+#define FAIL // fail the import if the field does not exist
