@section licensing_sec_1 CEGUI library licensing
The current version of CEGUI is licensed under the MIT License:
@verbinclude COPYING

Note that this license generally only covers the CEGUI code - either compiled
or in source code form.  For licensing information regarding the data and media
files that accompany CEGUI (under the datafiles directory), please see
@subpage datafile_licensing for additional information.

@section licensing_sec_3 Dependency licensing
- This sofware can be compiled to use the PCRE library by Philip Hazel.
PCRE is Copyright (c) 1997-2009 University of Cambridge, All rights reserved.
Please see @subpage pcre_lic for additional licensing information.
- This software can be compiled to use the Freetype2 library to provide most of
the font loading and rendering support.  Freetype2 is a free, high-quality, and
portable font engine; see http://www.freetype.org for more information.
- The Spinner widget contains some modified parts of the stringencoders library
(http://code.google.com/p/stringencoders).  Please see
@subpage stringencoders_lic for additional licensing that may apply to the use
of this component.
- This software can be compiled to optionally include an embedded copy of the
minibidi software from the Arabeyes project (http://www.arabeyes.org/).
minibidi was written by Ahmad Khalifa and is licensed under the MIT license.
- This sofware can be compiled to optionally contain an embedded version of
TinyXML.  Please see @subpage tinyxml_lic for additional licensing
information.
- This software can be compiled in such a way that certain components contain an
embedded copy of the OpenGL Extension Wrangler (GLEW) library.  Please see
@subpage glew_lic for additional licensing that may apply to the use of this
library.
- This software can be compiled to optionally contain an embedded copy of tolua++.
Please see the @ref toluapp_readme for additional information.
- This software can be compiled to optionally contain unzip code taken (and
modified) from the Minizip project.  The original Minizip code may be found at 
http://www.winimage.com/zLibDll/minizip.html
- This software can be compiled to contain an embedded version of the
stb_image.c code, which has been released into the public domain by it's author
Sean Barrett (http://nothings.org/).

@section licensing_sec_4 Licensing 101: What it all means!
While CEGUI itself is licensed under the MIT license, it is important that users
understand that you're probably not only using the CEGUI code, but also that of
certain other libraries that CEGUI is built on top of - this means that you may
have to additionally comply with the licensing of those other libraries and
components as well.

First I want to state that I'm not a 'license lawyer'; what follows is my
personal interpretaion of the licensing situation.  If you're in any doubt at
all, you should either directly contact the authors / license owners of the
specific components you have concerns about, or - if you have cash to
burn - consult a legal professional.

The exact way that you determine which of the external licenses you need to give
consideration to will largely depend upon the choices you make as regards to the
various options you have when building CEGUI.

At the very minimum you will need to consider CEGUI's MIT license and the BSD
license of the string encoders library (unless you do not compile the Spinner
widget code, in which case it's just CEGUI's MIT license).

The next two libraries that are nearly always used are PCRE and FreeType2.  With
MSVC++ builds using our provided dependency packages these libraries are always
linked in statically; while on the Mac using Xcode our provided dependency
packages use dynamic linking, although those component frameworks will generally
be distributed as part of your application.  This means that on both of these
systems you must comply with the license conditions for PCRE and FreeType2
(again, this only applies if you have not explicitly disabled the use of these
libraries).

If you enabled bi-directional text support using the integrated copy of the
minibidi code, then you need to consider the MIT license used for that code.

Beyond these items, the other libraries that you will consider will depend upon
your choices for renderering library, image codec library, XML parser and
scripting module.  Basically this means if you're not using - and therefore not
distributing - a particular module you do not need to worry about the licensing
any of the dependency libraries that module may use.

Generally the option modules use only the underlying library suggested in the
name of the module; for example, the XercesParser module only uses the
Xerces-C++ library and the FreeImageImageCodec uses FreeImage.  The only two
potential "gotchas" exist with the Lua based scripting module that can use an
embedded copy of the tolua++ code, and the OpenGL renderer module that can
contain a copy of the OpenGL extension wrangler library (GLEW).
