title: How to include option in dirsync python module?
body: <p>I have Python version 3.7.1.</p>
  <p>I would like to sync files with extension .835 in the source directory to the target directory. Why is this code pulling over all files?</p>
  <pre class="lang-py prettyprint-override"><code>import dirsync
  dirsync.sync(source,destination,'sync',verbose=True,only='.*\.835$')
  </code></pre>
  <p>I have also tried the --include option and pattern like this:</p>
  <pre class="lang-py prettyprint-override"><code>import dirsync
  pattern = r'.*\.835$'
  dirsync.sync(source,destination,'sync',verbose=True,include=pattern)
  </code></pre>
  <p>How do I solve this problem?</p>
