If you run a web server and have multiple installations of WordPress, upgrading them all is a pain.
Wouldn’t it be nice if you could update a dozen WP installs at once? Wouldn’t it be even better if you could update the Akismet plugin at the same time? (WordPress releases independently of Akimset, and their subversion tags doesn’t track Akismet’s trunk).
$ cd /path/to/wp-upgrade
$ sudo ./wp-upgrade.py 3.0.4
You need to configure two files before starting:
sites.txta tab-delimited file with information about the sites you’ll be upgrading (path, url, email address of owner, userid of owner)
wp-upgrade.txtan email with instructions to your users
