How do I include gl-matrix?

What I did: Downloaded master branch from here: https://github.com/toji/gl-matrix Put src folder into my project's folder. Included gl-matrix-manifest.js from there. Tried this: ``` var mvMatrix = mat4.create(); ``` Result: ``` var mvMatrix = mat4.create(); ReferenceError: mat4 is not defined ``` Okay, let's indlude mat4 directly. Included. Result: ``` var out = new GLMAT_ARRAY_TYPE(16); ReferenceError: GLMAT_ARRAY_TYPE is not defined ``` Okay, maybe it needs common.js: ``` var x = axis[0], y = axis[1], z = axis[2], TypeError: axis is undefined ``` WTF, included all other files from src folder (common, vectors,matrices,quat): ``` var x = axis[0], y = axis[1], z = axis[2], TypeError: axis is undefined ``` (same) How do I include propertly? In particular I need mat4 and vec4.
