+Cabal package format and follows different design principles.  Hpack packages
+are described in a file named @code{package.yaml}.  Both @code{cabal2nix} and
+@code{stack} support @code{package.yaml} natively.  For other build tools the
+@code{hpack} executable can be used to generate a @code{.cabal} file from
+@code{package.yaml}.")
