title: How to run a Grunt task after my Yeoman generator finishes installing?
body: <p>I'm building a custom Yeoman generator that installs a lot of pre-processed language compilers like CoffeeScript, LESS and Jade. In the Gruntfile that my generator creates I have a build task which compiles everything. However, until that build task is run at least once, the compiled HTML, CSS and Javascript files don't exist, which can be confusing if I try to run the grunt watch/connect server after freshly scaffolding.</p>
  
  <p>What is the best way to have my generator run that Grunt build step at the end of the installation? The <code>end</code> event that's already being used to call <code>this.installDependencies</code> seems like the right place to do that, but how should I communicate with Grunt?</p>
