Prompts from roles?

I know you can declare variables as part of a role:

└── wordpress-nginx ├── LICENSE.md ├── README.md ├── group_vars │ └── all ├── hosts.example ├── roles │ ├── common │ │ ├── files │ │ │ ├── RPM-GPG-KEY-EPEL-6 │ │ │ ├── epel.repo │ │ │ └── iptables-save │ │ ├── handlers │ │ │ └── main.yml │ │ └── vars │ │ └── main.yml

but can you specify vars_prompts under a role as well? I tried both vars_prompt/main.yml and prompts/main.yml but my ansible-playbook prompts me for neither. Running with Ansible 1.7.2.

I have many playbooks that all share the same role. The prompts are really specific to the role, not an individual playbook.

you can use the pause module to prompt for info and register a var
with the result var.user_input
