<h1>Check PHPlicensewatcher installation</h1>
<hr/>
<p>This will check whether PHPlicensewatcher has been properly installed. This is not an exhaustive check but checks for common installation and configuration issues.</p>
<p style="color: red;">When the script is finished with the check it will print out a congratulation message. If there is no congratulatory message a problem appeared that this script didn't anticipate :-(.</p>
