<p>Custom parser for GitLab-flavored <a href="Markdown.html">Markdown</a></p>
<p>It replaces references in the text with links to the appropriate items in
GitLab.</p>
<p>Supported reference formats are:</p>
<pre>* @foo for team members
* #123 for issues
* !123 for merge requests
* $123 for snippets
* 123456 for commits</pre>
<p>It also parses Emoji codes to insert images. See <a
href="http://www.emoji-cheat-sheet.com/">www.emoji-cheat-sheet.com/</a> for
a list of the supported icons.</p>
<p>Examples</p>
