### Compiler
I used to maintain a mirror that tracked the latest master, but nowadays, I
maintain a Docker image containing the specific compiler version that Vieter
builds with. Currently, this is V 0.3.2.
V is developed using a specific compiler commit that is usually updated
whenever a new version is released. Information on this can be found in the
[tools](https://git.rustybever.be/vieter-v/tools) repository.
