How to have a separate package or common module within DUB?

[Ian via Digitalmars-d-learn]

Hi,

Extremely basic question: I have a module that I want to share 
between different DUB-based executables. How do I put this in a 
different folder and point all the executables to share it? It 
doesn't necessarily have to be a library at this point (though 
that works too), as long as I can import the module.
