harvest is a small Go program that aggregates posts from the RSS feeds
of UPL member blogs into a single output/blog_posts.json and
output/feed.xml. Feeds are defined in whitelist.toml,
and a GitHub Actions workflow rebuilds the outputs every 12 hours,
but only when one or more whitelisted blogs have changed.
To add your blog, open a pull request against whitelist.toml (see
docs/CONTRIBUTING.md. To run it locally, go build -o harvest ./src
followed by ./harvest will fetch the listed feeds and write to
output/.
