Note that the OP is essentially talking about source distribution 
for use in rdmd scripts. So ABI is not an issue. This source 
could be installed as a Debian package, but since dub exists, the 
question is whether to use dub or not. If not, there'll be two 
parallel ways to install source. In any case, files should be 
written to system directories and it should be possible to 
uninstall.

The question originates from here:
