One useful characteristic of Stefan's images is that the 
Dockerhub pages include the Dockerfile and github repository 
links. I don't know what it takes to include them. It does make 
it easier to see exactly what the configuration is, find the 
repo, and even create PRs against them. Would be useful if they 
can be added to the CircleCI image pages.

My interest in this case - I use Stefan's LDC image in Travis-CI 
builds. Building the runtime libraries with LTO/PGO requires the 
ldc-build-runtime tool, which in turn requires a few additional 
things in the docker image, like cmake or ninja. I was interested 
if they might have been included in the CircleCI images as well.
