Tailor ansible roles to environment

Question

I have a number of environments, that require a bunch of text files to be tailored in order for things like mule to speak to the right endpoints.

For this environment, this works:

ansible-playbook test03.yml

The only difference between an environment (from ansible's perspective) is the information held in ./roles/esb/vars/main.yml.

I've considered using svn to keep a vars/main.yml for each environment, so each time I need to configure an environment I check out roles and then vars/main.yml for that environment, before I run the command above.

To me, not an elegant solution. How can I do this better?

Directory structure

./test03.yml
./roles/esb/vars/main.yml
./roles/esb/tasks/main.yml
./roles/esb/templates/trp.properties.j2

./test03.yml

---
- hosts: test03-esb
  gather_facts: no
  roles:
    - esb

./roles/esb/vars/main.yml

---
  jndiProviderUrl: 'jnp://mqendpoint.company.com:1099'
  trp_endpoint_estask: 'http://tmfendpoint.company.com:8080/tmf/estask'
  trp_endpoint_builderQ: 'jnp://mqendpoint.company.com:1099'

./roles/esb/tasks/main.yml

---
  - name: replace variables in templates
    template: src=trp.properties.j2  dest=/path/to/mule/deploy/conf/trp.properties

./roles/esb/templates/trp.properties.j2

trp.endpoint.estask={{ trp_endpoint_estask }}
trp.endpoint.builderQ={{ trp_endpoint_builderQ }}
