WordPress.org

Indigestion+ periodically collects a number of public RSS or Atom feeds and posts a list containing all new items. Each feed may provide additional display and metadata options, such as the ability to import comments or tags.

Indigestion+ began as a fork of the Indigestion plugin by Evelio Tarazona Cáceres, but eventually required a complete rewrite. It uses WordPress's "cron" function for scheduling and Simplepie to download, cache and manipulate feeds.
