<p>This plugin is great for someone needing to debug their own or another person’s WordPress site. It will collect and display and/or send debug information to an email address provided by the user.<br />
This is helpful for plugin or theme authors wanting to debug user’s sites.</p>
<p>Some features:</p>
<ul>
<li>Displays system information</li>
<li>Emails system information</li>
</ul>
<h3>Arbitrary section</h3>
<p>You may provide arbitrary sections, in the same format as the ones above.  This may be of use for extremely complicated<br />
plugins where more information needs to be conveyed that doesn’t fit into the categories of “description” or<br />
“installation.”  Arbitrary sections will be shown below the built-in sections outlined above.</p>
<h3>A brief Markdown Example</h3>
<p>Ordered list:</p>
<ol>
<li>Some feature</li>
<li>Another feature</li>
<li>Something else about the plugin</li>
</ol>
<p>Unordered list:</p>
<ul>
<li>something</li>
<li>something else</li>
<li>third thing</li>
</ul>
<p>Here’s a link to <a href="https://wordpress.org/" title="Your favorite software" rel="ugc">WordPress</a> and one to <a href="http://daringfireball.net/projects/markdown/syntax" title="Markdown is what the parser uses to process much of the readme file" rel="nofollow ugc">Markdown’s Syntax Documentation</a>.<br />
Titles are optional, naturally.</p>
<p>Markdown uses email style notation for blockquotes and I’ve been told:</p>
<blockquote>
<p>Asterisks for <em>emphasis</em>. Double it up  for <strong>strong</strong>.</p>
</blockquote>
<pre><code><?php code(); // goes in backticks ?>
</code></pre>

This plugin works but did not cleanup its table and data in options table in my DB.
