+/// @author Christophe Riccio
+///
+///	@defgroup core GLM Core
+///	
+///	@brief The core of GLM, which implements exactly and only the GLSL specification to the degree possible.
+///
+/// The GLM core consists of @ref core_types "C++ types that mirror GLSL types" and
+/// C++ functions that mirror the GLSL functions. It also includes 
+/// @ref core_precision "a set of precision-based types" that can be used in the appropriate
+/// functions. The C++ types are all based on a basic set of @ref core_template "template types".
+/// 
+/// The best documentation for GLM Core is the current GLSL specification,
+/// <a href="http://www.opengl.org/registry/doc/GLSLangSpec.4.20.8.clean.pdf">version 4.2
+/// (pdf file)</a>.
+/// There are a few @ref pg_differences "differences" between GLM core and GLSL.
+/// 
+/// GLM core functionnalities require <glm/glm.hpp> to be included to be used.
+/// 
+/// @defgroup core_types Types
+/// 
+/// @brief The standard types defined by the specification.
+/// 
+/// These types are all typedefs of more generalized, template types. To see the definiton
+/// of these template types, go to @ref core_template.
+/// 
+/// @ingroup core
+/// 
+/// @defgroup core_precision Precision types
+/// 
+/// @brief Non-GLSL types that are used to define precision-based types.
+/// 
+/// The GLSL language allows the user to define the precision of a particular variable.
+/// In OpenGL's GLSL, these precision qualifiers have no effect; they are there for compatibility
+/// with OpenGL ES's precision qualifiers, where they @em do have an effect.
+/// 
+/// C++ has no language equivalent to precision qualifiers. So GLM provides the next-best thing:
+/// a number of typedefs of the @ref core_template that use a particular precision.
+/// 
+/// None of these types make any guarantees about the actual precision used.
+/// 
+/// @ingroup core
+/// 
+/// @defgroup core_template Template types
+/// 
+/// @brief The generic template types used as the basis for the core types. 
+/// 
+/// These types are all templates used to define the actual @ref core_types.
+/// These templetes are implementation details of GLM types and should not be used explicitly.
+///

+/// @brief Handles the interaction between pointers and vector, matrix types.
+/// 
+/// This extension defines an overloaded function, glm::value_ptr, which
+/// takes any of the \ref core_template "core template types". It returns
+/// a pointer to the memory layout of the object. Matrix types store their values
+/// in column-major order.
+/// 
+/// This is useful for uploading data to matrices or copying data to buffer objects.
+///
+/// Example:
+/// @code
+/// #include <glm/glm.hpp>
+/// #include <glm/gtc/type_ptr.hpp>
+/// 
+/// glm::vec3 aVector(3);
+/// glm::mat4 someMatrix(1.0);
+/// 
+/// glUniform3fv(uniformLoc, 1, glm::value_ptr(aVector));
+/// glUniformMatrix4fv(uniformMatrixLoc, 1, GL_FALSE, glm::value_ptr(someMatrix));
+/// @endcode
+/// 
+/// <glm/gtc/type_ptr.hpp> need to be included to use these functionalities.
