Can I use dub to build multiple app.d files?

[Selim]

Hi there. I have been using dub for a while now -maybe 12 months- 
but I haven't been able to figure out if you can build multiple 
app.d files with it. Is it possible to use dub run command to 
build multiple executables in one shot?

Maybe the question is weird, because dub might not be the tool to 
do that sort of thing. In that case, I would appreciate pointers.

Thanks,
Selim
