Automatically sort dependencies

[Alex7Li]

When using this library, I have a lot of goog modules which have to be compiled in a certain order, and i need to list all of them in the correct order for karma to work. This is somewhat annoying, because every time a file is added I have to put just that file in my karma config. For example if I have goog modules a,b,c where c requires b requires a, then I need to write

module.exports = function(config) {
  config.set({
    files: ['src/a.js', 'src/b.js', 'src/c.js', 'test/*_test.js'],
    preprocessors: {'**.js': ['googmodule']},
    plugins: [
      require('karma-googmodule-preprocessor'),
    ],
  })
};

Rather than just being able to say files:[src/**.js]. I'm wondering if it's possible to add this feature, or, if it exists documentation about how to do it correctly.
