I’ve just released a new version of subatom, that now gets linking correct if you have viewcvs or similiar installed. Unfortunately, I’ve now realised that the amount of command line arguments are such that I’m going to have to start adding a configuration file to it. My crontab lines are looking a bit unwieldy.
Nonetheless, if you want to generate atom feeds of your subversion repository, give it a try. It seems to work quite well.
