 Low level bindings to [libpci](https://github.com/pciutils/pciutils)
 See also the pciutils [homepage](https://mj.ucw.cz/sw/pciutils/).
 
 This package uses [bindings-DSL](http://hackage.haskell.org/package/bindings-DSL) and conforms to its naming convention.
 
-For a higher-level and more Haskell friendly binding (which uses this package) see the [pci](https://github.com/standardsemiconductor/pci) package.
