+ * Remove pages with only 1 revision from the MediaWiki namespace, without
+ * flooding recent changes, delete logs, etc.
+ * Irreversible (can't use standard undelete) and does not update link tables
+ *
+ * This is mainly useful to run before maintenance/update.php when upgrading
+ * to 1.9, to prevent flooding recent changes/deletion logs. It's intended
+ * to be conservative, so it's possible that a few entries will be left for
+ * deletion by the upgrade script. It's also possible that it hasn't been
+ * tested thouroughly enough, and will delete something it shouldn't; so
+ * back up your DB if there's anything in the MediaWiki that is important to
+ * you.
