-- ^ The packages depended on which already exist
, configPromisedDependencies :: [PromisedComponent]
-- ^ The packages depended on which doesn't yet exist (i.e. promised).
-- Promising dependencies enables us to configure components in parallel,

-- For example, in multi-repl mode, we don't want to build dependencies that

, configDebugInfo :: Flag DebugInfoLevel

, configDumpBuildInfo :: Flag DumpBuildInfo
-- ^ Should we dump available build information on build?
-- Dump build information to disk before attempting to build,
-- tooling can parse these files and use them to compile the
-- source files themselves.
, configUseResponseFiles :: Flag Bool
-- ^ Whether to use response files at all. They're used for such tools
-- as haddock, or ld.
, configAllowDependingOnPrivateLibs :: Flag Bool
-- ^ Allow depending on private sublibraries. This is used by external
-- tools (like cabal-install) so they can add multiple-public-libraries
-- compatibility to older ghcs by checking visibility externally.
, configCoverageFor :: Flag [UnitId]
-- ^ The list of libraries to be included in the hpc coverage report for
-- testsuites run with @--enable-coverage@. Notably, this list must exclude
-- indefinite libraries and instantiations because HPC does not support
-- backpack (Nov. 2023).
, configIgnoreBuildTools :: Flag Bool
-- ^ When this flag is set, all tools declared in `build-tool`s and
-- `build-tool-depends` will be ignored. This allows a Cabal package with
-- build-tool-dependencies to be built even if the tool is not found.
