Running:

• You need to set your feed and your twitter account.
• You need to create a configuration file. You can see a sample with the command feed2twitter -p. It will looks like:

[global]
url = http://example.com/rss
username = twitter_user
password = twitter_password
mode = text
interval = 01:00
items = 5

The url is the url for the feed that you want to publish, mode can be 'text' (140 chars of your post text) or 'title' (your post title, with a link). The interval is the interval in which the feed2twitter will publish your last posts. In the sample, feed2twitter will check the provided feed each hour.

Run it with the command feed2twitter. It will update your twitter with your latest posts, in the interval that you have set.

Kudos to Gleicon da Silveira (http://zenmachine.wordpress.com/about/), that give me a idea of the code in a post of his blog.
