Feature: Allow multiple sources to be setup.
Scenario: Three source directories.
Given the Server is running at "multiple-sources-app"
When I go to "/index.html"
Then I should see "Default Source"
When I go to "/index1.html"
Then I should see "Source 1"
When I go to "/index2.html"
Then I should see "Source 2"
When I go to "/override-in-two.html"
Then I should see "Overridden 2"
When I go to "/override-in-one.html"
Then I should see "Opposite 2"
Scenario: Three data directories.
Given the Server is running at "multiple-data-sources-app"
When I go to "/index.html"
Then I should see "Default: Data Default"
Then I should see "Data 1: Data 1"
Then I should see "Data 2: Data 2"
