Hi, I'm new to D and I would like to get the dlang-tour onto my local machine. As far as I know, on my Pinebook Pro using aarm64 architecture, I must use the LDC compiler. The dlang-tour readme says to run `dub run dlang-tour -- --lang-dir .` which will run `rdmd` commands. Is there a way to tell dub to work with ldc instead? Thanks for your help!
