Twitter gem documentation?

I've just started a new project using the twitter gem http://twitter.rubyforge.org/ I've managed to authenticate a user and create an object out of it. Then I've pulled that user's timeline and created an array out of their tweets. Now I'd like to find a way to parse specific information out of each tweet but I can't find a list of relevant methods. I'd like to do something like:

tweets.each {|tweet| puts tweet.text                                      puts tweet.location                                      puts tweet.created_at}

Am I doing this wrong? Is there another way to parse out this information?
