Exactly! I have found that as well. I had always thought that the whole default module mapper is embedded in GCC source, but when I started to look into that I immediately found the standalone `g++-module-server` executable. I'll implement this `-R` thing there, and try to have Autotools working with modules in this way. We'll see how things roll out.
