Distribution.Simple.Build.Macros
Description
Generate cabal_macros.h - CPP macros for package version testing
When using CPP you get
VERSION_<package> MIN_VERSION_<package>(A,B,C)
for each package in build-depends, which is true if the version of
package in use is >= A.B.C, using the normal ordering on version
numbers.
Documentation

generatePackageVersionMacros :: [PackageIdentifier] -> StringSource
Helper function that generates just the VERSION_pkg and MIN_VERSION_pkg
macros for a list of package ids (usually used with the specific deps of
a configured package).
