I use my RSS aggregator as a filing system for interesting articles. I know this isn't what RSS was designed for, but I suspect I'm not alone in this use model. Unfortunately, it makes it difficult to switch to a new reader, because the new application would only know about recent and new articles, and wouldn't know about flagged articles, etc.

I wanted to switch to Vienna from NetNewsWire (thanks Steve!), but first I had to find a way to migrate my NNW data. I didn't find one, so I wrote one. It was supposed to be a couple hours of work, but it turned into more than that...I hope it's useful to someone else.

Warning: this script requires a few Perl modules (DBI, DBD::SQLite, and XML::Parser), as well as the expat XML library. I have included instructions for installing them in the comments of the script. If the instructions are unclear, please post questions here.
