@ -568,10 +568,10 @@ Role dependencies can also be specified as a full path, just like top level role
dependencies:
- { role: '/path/to/common/roles/foo', x: 1 }
Roles dependencies are always executed before the role that includes them, and are recursive.
Role dependencies may be included more than once. Continuing the above example, the 'car' role could
add 'wheel' dependencies as follows::
Roles dependencies are always executed before the role that includes them, and are recursive. By default,
roles can also only be added as a dependency once - if another role also lists it as a dependency it will
not be run again. This behavior can be overridden by adding `allow_duplicates: yes` to the `meta/main.yml` file.
For example, a role named 'car' could add a role named 'wheel' to its dependencies as follows::

- { role: wheel, n: 3 }
- { role: wheel, n: 4 }
If the wheel role required tire and brake in turn, this would result in the following execution order::
And the `meta/main.yml` for wheel contained the following::

allow_duplicates: yes
dependencies:
- { role: tire }
- { role: brake }
The resulting order of execution would be as follows::
tire(n=1)
brake(n=1)

As of Ansible 1.2, you can also pass in extra vars as quoted JSON, like so::
--extra-vars "{'pacman':'mrs','ghosts':['inky','pinky','clyde','sue']}"
--extra-vars '{"pacman":"mrs","ghosts":["inky","pinky","clyde","sue"]}'
The key=value form is obviously simpler, but it's there if you need it!
