Subject: what does the 'it' do?

I came across the following code (see below). As President Clinton
famously said, "It depends on what the definition of 'it' is." I am
hoping someone can explain how 'it' is being used. I have come across
this 'it...string...do' construct before, but I didn't understand it
then either.

describe IowaRubyBrigade do
  before do
    @irb = Array.new
  end

  it "should be a user group" do
    @irb.should be_a_kind_of(UserGroup)
  end

  it "should meet monthly" do
    @irb.meeting_time.should ==
      'second Thursday of every month'
  end

  it "should be fun" do
    @irb.should be_fun
  end
end

When you ri it, you get:

----------------------------------
Spec::Example::ExampleGroupMethods#it
     it(description=nil, &implementation)
------------------------------------------------------------------------
     Creates an instance of Spec::Example::Example and adds it to a
     collection of examples of the current example group.


     (also known as specify)


But the documentation on Spec is difficult to find. Please educate me.
Thanks,
