I looked at a few online services that provide custom created RSS feeds for websites that don't have one. None of them were free of charge without being too much limited in functionality for me.

So I hacked together this very simple rssify.py script. It reads from a config file your websites you want to rssify. It could be easily extened for more features if needed. For now it only parses the title and date via css selectors and generates a feed.xml file which can be imported into newsboat/newsbeuter or I guess any other rss reader.

The script runs once daily in a cronjob on my local machine.
