<p>This plugin allows developers to debug PHP errors.</p>
<p><em>Features for Developers</em></p>
<ul>
<li>You can get call stack trace when PHP errors are triggered.</li>
<li>This is particularly helpful in finding errors that are triggered by the WordPress deprecation and<br />
doing_it_wrong code.  These errors are reported in the WordPress core instead of at the location<br />
where the incorrect usage actually occurs. </li>
<li>You can set the error level from the Settings page, the default is trap Notice and Deprecation errors</li>
</ul>
<p><em>Additional Features</em></p>
<p>There are no additional features supported by Simple Error Handler.  The code is simple, small and well documented,<br />
so you can use it as a starting point for your own error reporting or logging plugin.</p>
