Bierbot is a project mainly written in Ruby, it's free.
Publish updates from the Bier Brewery website of new biers
Automatically grabs bier updates from the Bier Brewery website (http://www.bierbrewery.com/) and publishes them to the Bierbot twitter feed. Mostly just HTML surgery, so prone to failure, fits of spontaneous anger, and spectacular flameouts.
Requires your Twitter creds to be specfied in a .bier_bot_auth YAML file of the form:
consumer_key: "app consumer key" consumer_secret: "app consumer secret" oauth_token: "oauth token" oauth_token_secret: "oauth token secret"
