# README
This repo explores the possibilities to achieve a module-wise conditional building without resorting to CPPs.
## `only-reexported-modules`
Uses `reexported-modules` section of Cabal to achieve conditional building.
### Pros
* Works both with Stack and Cabal
* No extension required
### Cons
* The package using `reexported-modules` cannot call the re-exported module with the renamed module name.
## separate-backpacks
### Pros
* Can statically check module signatures
* Underlying packages can refer to the switched modules.
### Cons
* Won't work with Stack
* Too many separate packages!
## backpack-single
### Pros
* Same as the separate one
* Only one user-facing library package!
### Cons
* Haddock doesn't support reexported-modules
* Stack won't work
