This is a tool for generating a webring from RSS feeds, so you can link to other blogs you like on your own blog. It's designed to be fairly simple and integrate with any static site generator. The basic usage is:
-s https://drewdevault.com/feed.xml \
-s https://emersion.fr/blog/rss.xml \
-s https://danluu.com/atom.xml \
< in.html \
This will read the template at in.html (an example is provided, but feel free to adjust it to suit your needs), fetch the latest 3 articles from among your sources, and pass them to the template and write the output to out.html. Then you can include this file with your static site generator's normal file include mechanism.
