# Bootstraps from an empty cabal to all the necessary haskell packages
# being installed, with the necessary patches to work on Android.
#
# You should install ghc-android first.
#
# The cabal.config is used to pin the haskell packages to the last
# versions that have been gotten working. To update, delete the
# cabal.config, run this script with an empty cabal and fix up the broken
# patches, and then use cabal freeze to generate a new cabal.config.
