Ansible 1.3 Conditional Execution -- Very complete example with comments -- I find the conditional expressions to be ridiculously hard to get right in Ansible.

# 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"
# NB: The type of the variable is crucial!
