| 11 | # 2006-08-07 (ADH): It seems the core RSS features are easily sufficient | |
| 12 | # so fun though Simple-RSS was, it makes sense to use | |
| 13 | # something that doesn't add extra dependencies. Moved | |
| 14 | # over to the Ruby RSS parser. Since tags get expanded | |
| 15 | # before filters run, but there is no way to escape | |
| 16 | # text filtered by (say) Textile, instead get rid of | |
| 17 | # characters known to be a problem. | |

| defaults to '4'. The 'dates' attribute is optional; it says whether | ||
| or not article dates (if found) will be added in small text after | ||
| each headline. If '0' there are no dates, else dates are shown. The | ||

| 36 | feed's "pubDate", "modified" or "dc_date" fields, in that order. | |
