Pulp

Running:
ansible-playbook example-use/playbook.yml -u <user> -K --ask-pass returns following error:

ERROR! the role 'pulp-database' was not found in /home/ansible/ansible-pulp/example-use/roles:/home/ansible/.ansible/roles:/usr/share/ansible/roles:/etc/ansible/roles:/home/ansible/ansible-pulp/example-use

The error appears to have been in '/home/ansible/ansible-pulp/example-use/playbook.yml': line 4, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

roles:
  - pulp-database
    ^ here

Ansible is run locally.

How to fix: copy /roles directory into example-use/ directory
