There's a relatively new (and possibly undocumented) feature in  
cucumber[1] where you can call steps from within other steps.

So for example, you can have one scenario like this:

     Scenario: Log in as admin
	Given I visit the login page
	And I enter the username "matt"
	And I enter the password "secret"
	And I press "Submit"
	Then I should be on the admin page


And another one like this:
     Scenario: View admin reports
	Given I log in as admin
	And I view the reports page
	Then I should see "reports"

When you write the ruby step matcher for the first step in this  
scenario, you just call the step matchers that you wrote for the first  
scenario, like this:

Given /I log in as admin/ do
   Given "I visit the login page"
   Given 'I enter the username "matt"'
   Given 'I enter the password "secret"'
   Given 'I press "Submit"'
end

Does that make sense? Does it help?

cheers,
Matt
