Notice that though hxput and hxsel need the packages in the top-level build-depends, they don't need to declare it.Thanks. From documentation it was not clear this feature. However, what happens if hxput add a build-depends field? Will this override the "global" field? Manlio Perillo
It doesn't override, but adds to. If the toplevel declares 'base', and then hxput does 'build-depends: random', hxput will be built against 'base, random'. -- gwern
