`.gitlab-ci.yml`
----------------

To build with several images:
```
---
dune:2.3--gcc:
  image: duneci/dune:2.3
  script:
  - configure
  - build

dune:2.3--clang:
  image: duneci/dune:2.3
  script:
  - configure CXX=/usr/bin/clang++
  - build
```

You can also specify a default image and use it in several jobs:

```
---
image: duneci/dune:2.4

dune:2.4--gcc:
  script:
  - configure
  - build

dune:2.4--clang:
  script:
  - configure CXX=/usr/bin/clang++
  - build
```
