This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (gl-mat3) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
gl-mat3 
Part of a fork of @toji's
gl-matrix split into smaller pieces: this
package contains glMatrix.mat3.
Usage
mat3 = require('gl-mat3')
Will load all of the module's functionality and expose it on a single object. Note that any of the methods may also be required directly from their files.
For example, the following are equivalent:
var scale = require('gl-mat3').scale
var scale = require('gl-mat3/scale')API
