While I was on the road last week, I really felt the loss of my NetNewsWire subscription information: I had the software on my TiBook, but without my most current list of RSS feed subscriptions, I was left somewhat as a fish out of water. I can explicitly export a subscription list from NetNewsWire into OPML format, but I wanted something more automatic. So I wrote limpet, a simple C program that automates the creation of these OPML subscription files. With an additional script from my upcoming Wicked Cool Shell Scripts, I can now keep an up-to-date copy of my subscriptions list on my server without even thinking about it. If you’re a NetNewsWire user, you’ll want to check out limpet today!
