He, thanks!
What about sharing configuration options?
I mean what happens if the main library, the application and the test
application all need

Library :
        build-depends: foo, blaa, blahh , booh, banana, food, some, more ?

Executable foo
        build-depends: foo, blaa, blahh , booh, banana, food, some, more ?

Executable test
        build-depends: foo, blaa, blahh , booh, banana, food, some, more ?

Is there a way to specify the list only once?
