title: Gulp not creating any files
body: <p>I created a project for becoming familiar with build tools. My folder structure for this project looks like so:</p>
  
  <pre><code>+ my-project
  |-- + sources
  |------ index.html
  |-- + www
  |-- gulpfile.js
  </code></pre>
  
  <p>And the contents of <code>glupfile.js</code> are:</p>
  
  <pre><code>var gulp = require('gulp');
  
  gulp.task('default', function() {
      gulp.src('sources/index.html')
      .pipe(gulp.dest('www/index.html'));
  });
  </code></pre>
  
  <p>For simplicity's sake I <code>chmod</code>'d everything in this folder (and all parent folders) to <code>777</code> - so there's no issue of file permissions.</p>
  
  <p>Yet when I run <code>gulp</code>, I get the following output:</p>
  
  <pre><code>user@server:~/my-project# gulp
  [00:05:09] Using gulpfile ~/my-project/gulpfile.js
  [00:05:09] Starting 'default'...
  [00:05:09] Finished 'default' after 11 ms
  </code></pre>
  
  <p>and absolutely no files are created. The <code>www</code> folder remains barren.</p>
  
  <p>What am I doing wrong?</p>
