# - Creates an isolated build environment to test whether the toolchain

# requirements stated in dub.sdl are up to date.

# - The image should build successfully if and only if the project is buildable

# with the stated minimum versions of all 3 toolchains.

# - The build environment should be as close as possible to the one used by

# Travis CI builds to help run experiments and predict whether the continuous

# integration builds will succeed or fail.
