Hi Andre,

your solution solved the problem. Thanks.

Reading again the error message, with the solution at hand, I 
think your answer may be completed. I explain:
The message was:

source/app.d(9,8): Error: module dterrent is in file 'dterrent.d' 
which cannot be read

I think dub looked for a dterrent.d file in registered paths. 
Then it also looked for a dterrent directory in paths, possibly 
verifying that a package.d file was present in that directory. 
Finding neither nor, it concluded that the module should have 
been in an eponymous dterrent.d file somewhere, and displayed 
that ambiguous error message.

So it seems that dub does not parse any file looking for the line 
"module dterrent;" as I thought. It just looks for a file or 
directory named dterrent(.d) Maybe it also verify that an 
eponymous folder has a package.d, in this case we can say "a 
folder must have a normative package.d file".

Maybe.
Thanks again for your fast answer.
