auto generate scoped versions of your webrat steps

gistfile1.rb

# Stick this in features/step_definitions/scoped_webrat_steps.rb
#
# If your webrat steps defines:
#
#   When /^I press "(.*)"$/ do |link|
#     clicks_link(link)
#   end
#
# Then this will also define:
#
#   When /^within: (.*?), I press "(.*)"$/ |scoped, link|
#     within(scope) {|s| s.clicks_link(link)}
#   end
#
# When means you can do stuff like this:
#
# Scenario: click the 'home' in the crumbs bar
#   When within: div#crumbs, I press "home"
#   ...
