My CVS Workflow for Updating a Theme on drupal.org
From time to time, I've had to update my airyblue project in CVS (Airy Blue is a light, airy, Zen subtheme listed on Drupal.org's Themes section). It's always a bother, and I always end up spending about 20 minutes figuring out how to check out the module to my local computer (I use three of them, so even if I have it set up on one, I need to get it going on another sometimes), then another 20 figuring out how to commit my changes, tag a release, etc.
So, this post might be titled "How to Maintain a Theme on Drupal.org if You're Confounded by the CVS Guide for Theme Maintainers, and you are on a computer on which you haven't checked out your module yet."
