Just hacked together a small Python script to automatically update Chromium on my Mac to the latest SVN revision. I wrote this around 2am, so don’t expect bells and whistles. You can download it here:

The script is public domain, meant to be run interactively and provided without any warranties or batteries. It may or may not do bad things to your house and your cat, but mostly it just updates Chromium.
