If grabbed via rt_configOption, the DRT options are read from the environment variable "DRT_<OPT>" if rt_envvars_enabled is set in the binary. See https://dlang.org/spec/garbage.html#gc_config for an example.

Let's keep this open and change the purpose? Improving the documentation? For example, we could add a dedicated page about druntime's option to the spec.

Great idea! We actually I think should summarize in a nice document all the ways you can customize druntime, command line, environment, and in the binary.

I recently found a start in rt.config. But I'm not sure, if that's complete:

I think that's the wrong place to document. They should be documented elsewhere (but the document should be linked), because the options are scattered all over the place (GC, cycle detection, unittest, etc.).

One document to show how to USE the DRT options should be a nice top-level article.
