将自定义JS和CSS文件添加到自定义Yeoman生成器

Question

我正在尝试构建一个自定义的yeoman生成器，而且我的基础是来自yeoman的webapp生成器。如果未选择bootstrap，我需要知道如何添加某些js和css文件。这些文件当前与我的index.html文件以及main.css存储在同一级别。

我已经测试了发生器，一切正常，我无法弄清楚如果添加某些文件或者如果存在bootstrap则将它们排除。任何帮助是极大的赞赏。

请在投票前提问。这是我第一次搞乱自定义生成器。

下面是我的index.js文件：

'use strict';

var join = require('path').join;
var yeoman = require('yeoman-generator');
var chalk = require('chalk');

module.exports = yeoman.generators.Base.extend({
  constructor: function () {
    yeoman.generators.Base.apply(this, arguments);

    // setup the test-framework property, Gruntfile template will need this
    this.option('test-framework', {
      desc: 'Test framework to be invoked',
      type: String,
      defaults: 'mocha'
    });
    this.testFramework = this.options['test-framework'];

    this.option('coffee', {
      desc: 'Use CoffeeScript',
      type: Boolean,
      defaults: false
    });
    this.coffee = this.options.coffee;

    this.pkg = require('../package.json');
  },

  askFor: function () {
    var done = this.async();

    // welcome message
    if (!this.options['skip-welcome-message']) {
      this.log(require('yosay')());
      this.log(chalk.magenta(
        'Out of the box I include HTML5 Boilerplate, jQuery, and a ' +
        'Gruntfile.js to build your app.'
      ));
