modernizr/src/Modernizr.js

Modernizr is a JavaScript library that detects HTML5 and CSS3 features in the user’s browser.

define(['ModernizrProto'], function( ModernizrProto ) {
  // Fake some of Object.create
  // so we can force non test results
  // to be non "own" properties.
  var Modernizr = function(){};
  Modernizr.prototype = ModernizrProto;

  // Leak modernizr globally when you `require` it
  // rather than force it here.
  // Overwrite name so constructor name is nicer :D
  Modernizr = new Modernizr();

  return Modernizr;
});
