	The strip index generation is now complete. If no errors were reported above
	then you should check the integrity of the generated strip index. First look
	at your <a href="index.php">admin index page</a> to ensure all the strip dates and titles are correct.
	You should also check that the strip images are correct as well. If this check
	reveals no problems then you should next check that there are no orphaned files
	in the strip and news directories. To do this, run the <a href="checkfs.php">filesystem
	check</a> from
	the admin index page. If this check reveals no problems then you should delete
	this script from your server as it is no longer needed. If, however, you find
	a problem then you may need to run this script again after taking the appropriate
	corrective action. See the iStrip documentation for more details on troubleshooting
	this script for more details. </td>
