rawdog is an RSS feed aggregator… I looked at a few PHP based RSS libraries this morning and loaded a few of them up to try them out. Then found this Python based tool set which looks a little more powerful.
The project write-up says: rawdog is an RSS Aggregator Without Delusions Of Grandeur. Written in Python, it uses Mark Pilgrim’s feed parser to read RSS 0.9, 1.0, 2.0, CDF and Atom feeds. It runs from cron, collects articles from a number of feeds, and generates a static HTML page listing the newest articles in date order. It supports per-feed customisable update times, and uses ETags, Last-Modified, and gzip compression to minimise network bandwidth usage.
