  // This is an attempt to make this library compatible with multiple module
  // formats. Other UMD implementations do not take into account dependencies:
  // Example: https://github.com/ForbesLindesay/umd/blob/master/template.js

  // **NOTE: Named AMD modules are more suitable for libraries as it provides
  // a consistent naming convention to access it by (anonymous AMD modules are
  // better suited on an app level where files/paths may be changed).

    };

    module.exports = definition.apply(context, deps);

I just released AMDClean 1.2.1, which added the prefixMode option. You can now have all of your modules use camelCase instead of underscores. If that's not enough, you can use the new prefixTransform function hook to customize the logic yourself.

Usually, the Require.js shim configuration will work (but there are exceptions). AMDClean depends on the escodegen library, which does not work even with the shim configuration: estools/escodegen#115 (comment)

The AMDClean approach still works (even though Escodegen does not work with Require.js), since it also checks if there is a global window.escodegen object that is declared (which there is) and a window.escodegen.generate method.
