150	<p>It appears that you have installed FeedWordPress
151	<?php echo FEEDWORDPRESS_VERSION; ?> as an upgrade to an existing installation of
152	FeedWordPress. That's no problem, but you will need to take a minute out first
153	to upgrade your database: some necessary changes in how the software keeps
154	track of posts and feeds will cause problems such as duplicate posts and broken
155	templates if we were to continue without the upgrade.</p>
156
157	<p>Note that most of FeedWordPress's functionality is temporarily disabled
158	until we have successfully completed the upgrade. Everything should begin
159	working as normal again once the upgrade is complete. There's extraordinarily
160	little chance of any damage as the result of the upgrade, but if you're paranoid
161	like me you may want to back up your database before you proceed.</p>
162
163	<p>This may take several minutes for a large installation.</p>
