title: How to print out a text once grunt task completes?
body: <p>Once a Grunt task completes, I want to print out some information. See the Grunt snippet below.</p>
  
  <p>Is there a way to achieve this? I noticed that <code>grunt.task.run()</code> does not support callbacks. This causes my message to be printed out prior to coverage report output.</p>
  
  <pre><code>grunt.registerTask('coverage', 'Runs all unit tests available via Mocha and generates code coverage report', function() {
      grunt.task.run('env:unitTest', 'mochaTest');
  
      grunt.log.writeln('Code coverage report was generated into "build/coverage.html"');
  });
  </code></pre>
  
  <p>I also want to avoid "hacks" such as creating a grunt task only for printing the information out and adding it to the <code>grunt.task.run()</code> chain of tasks.</p>
