# This has been tested with ansible 1.3 with these commands:
#   ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=false"
#   ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=true"
#   ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts"
