# To use, mainly change the list in 'plans' and modify 'include' for
# any OS package manager deps.
#
# Currently not working for cabal-install >= 3
#
# Based on https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/travis-complex.yml
#
# TODO:
# * cache (https://github.com/actions/cache)
#     but this is too small. native cacheing will come soon
#     https://github.community/t5/GitHub-Actions/Caching-files-between-GitHub-Action-executions/m-p/30974/highlight/true#M630
#     so we can wait for then.
# * support for cabal-install >= 3
