Sorry,
the documentation doesn't allow me to understand easily, how to 
use it without additional pain. The link you gave doesn't 
describe a clear method for those, who never used dub before.
Anyway... I was able to solve my problem in a convenient for me 
way (using #!/usr/bin/rdmd --shebang -version=test -O)

Thank you anyhow!
