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.

Synopsis

- generate :: PackageDescription -> LocalBuildInfo -> String
- generatePackageVersionMacros :: [PackageIdentifier] -> String

# Documentation

generate :: PackageDescription -> LocalBuildInfo -> String

The contents of the `cabal_macros.h` for the given configured package.

generatePackageVersionMacros :: [PackageIdentifier] -> String

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).
