21 -# USAGE: once FeedWordPress is installed, you manage just about everything from
22 -# the WordPress Dashboard, under the Syndication menu. To ensure that fresh
23 -# content is added as it becomes available, you can convince your contributors
24 -# to put your XML-RPC URI (if WordPress is installed at
25 -# <http://www.zyx.com/blog>, XML-RPC requests should be sent to
26 -# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the
27 -# Syndication menu, or set up automatic updates under Syndication --> Settings,
28 -# or use a cron job.

1539 - * blog at the time -- usually meaning no user at all. But if WordPress
1540 - * gets a wp_insert_post() when current_user_can('unfiltered_html') is
1541 - * false, it will run the content of the post through a kses function
1542 - * that strips out lots of HTML tags -- notably <object> and some others.
1543 - * This causes problems for syndicating (for example) feeds that contain
1544 - * YouTube videos. It also produces an unexpected asymmetry between
1545 - * automatically-initiated updates and updates initiated manually from
1546 - * the WordPress Dashboard (which are usually initiated under the
1547 - * credentials of a logged-in admin, and so don't get run through the
1548 - * kses function). So, to avoid the whole mess, what we do here is
1549 - * just forcibly disable the kses munging for a single syndicated post,
1550 - * by restoring the contents of the `post_content` field.
1644 + * Postcondition: If $rss is the URL of a feed not yet on FWP's list of

1646 + * as its initial title and $uri as its initial homepage URL (normally
1647 + * these will be updated with new values taken from the feed, the first
1648 + * time the new feed is checked for syndicated content, unless feed
1649 + * settings prevent this). If $rss is the URL of a feed that is already
1650 + * on FWP's list of subscribed feeds, then that feed will be updated to
1651 + * use the title provided in $name and the homepage URL in $uri
1551 1652 *
1552 - * @param string $content The content of the post, after other filters have gotten to it
1553 - * @return string The original content of the post, before other filters had a chance to munge it.
1653 + * @param string $name The human-readable title of the feed (for example, "Rad Geek People's Daily")
1654 + * @param string $uri The URI for the human-readable homepage associated with the feed (for example, <http://radgeek.com/>)
1655 + * @param string $rss The URI for the feed itself (for example, <http://radgeek.com/feed/>)
1656 + *
