Digest Post fetches an RSS feed on a regular basis (usually daily) and posts a
list of links to the newest articles as a digest post to your blog.
In order to run daily, it leverages the WordPress “cron” facility which was
introduced in WordPress 2.1. Therefore, this plugin won’t work with any versions
older than that.
Please note that this plugin is in a very early stage of development. It
currently has no Admin pages to configure it with, instead you need to go into
the plugin’s PHP code to set it up. However it is planned to have it completely
configurable through a WordPress Admin page.
