atb_customize_feeds allows you to modify Textpattern’s article syndication feeds by creating a few new forms that are either parsed and appended to your feeds, or which replace article bodies and excerpts in feeds.

Possible uses include appending file enclosures to your feeds (for podcasts, for example), generating excerpts with <a href="http://www.wilshireone.com/textpattern-plugins/rss_auto_excerpt">rss_auto_excerpt</a>, or appending permlinks to your articles’ text.

(Written and tested on Textpattern 4.2.0. Everything should work in any version since 4.0.4, but I make no promises…)
