description: |
    @ghc-source-gen@ is a library for generating Haskell source code.
    It uses the <https://hackage.haskell.org/package/ghc ghc> library
    to support recent language extensions, and provides a simple, consistent
    interface across several major versions of GHC.
    .
    To get started, take a look at the "GHC.SourceGen" module.
    .
    For more information, please see the <https://github.com/google/ghc-source-gen README>.
