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?
