- * Display the post content for the feed.
- *
- * For encoding the html or the $encode_html parameter, there are three possible
- * values. '0' will make urls footnotes and use make_url_footnote(). '1' will
- * encode special characters and automatically display all of the content. The
- * value of '2' will strip all HTML tags from the content.
- *
- * Also note that you cannot set the amount of words and not set the html
- * encoding. If that is the case, then the html encoding will default to 2,
- * which will strip all HTML tags.
- *
- * To restrict the amount of words of the content, you can use the cut
- * parameter. If the content is less than the amount, then there won't be any
- * dots added to the end. If there is content left over, then dots will be added
- * and the rest of the content will be removed.
