 ----------------------
-Documentation for all glMatrix functions can be found [here](http://glmatrix.net/docs/2.0.0/)
-
-What's new in 2.0?
--------------------------
-glMatrix 2.0 is the result of a lot of excellent feedback from the community,
-and features:
-
- - Revamped and consistent API (not backward compatible with 1.x, sorry!)
- - New functions for each type, based on request.
- - New array operations: vec(2/3/4).forEach
- - Even more optimizations!
- - A cleaner code base, broken up by type.
- - A more complete unit testing suite.
-
-Looking for an older version?
------------------------------
-You can download previous versions of glMatrix [here](https://github.com/toji/gl-matrix/tags)
-
-A note about Matrix formatting
-------------------------------
-glMatrix is modeled after the needs of WebGL, which in turn uses matrix
-conventions set by [OpenGL](http://www.opengl.org/archives/resources/faq/technical/transformations.htm).
-Specifically, a 4x4 matrix is an array of 16 contiguous floats with the 13th,
-14th, and 15th elements representing the X, Y, and Z, translation components.
-
-This may lead to some confusion when referencing OpenGL documentation, however,
-which represents out all matricies in column-major format. This means that while
-in code a matrix may be typed out as:
-
-    [1, 0, 0, 0,
-     0, 1, 0, 0,
-     0, 0, 1, 0,
-     x, y, z, 0]
-
-The same matrix in the [OpenGL documentation](http://www.opengl.org/sdk/docs/man2/xhtml/glTranslate.xml)
-is written as:
-
-    1 0 0 x
-    0 1 0 y
-    0 0 1 z
-    0 0 0 0
-
-Please rest assured, however, that they are the same thing! This is not unique
-to glMatrix, either, as OpenGL developers have long been confused by the
-apparent lack of consistency between the memory layout and the documentation.
-
-Sorry about that, but there's not much I can do about it.
