# Fairly thorough tests on windows.
# Runs on notable pushes to ci-windows, and weekly on master.
# Builds all modules optimised, runs unit, doc tests,
# and uploads binaries artifact.

# Light Windows CI tests: build and run functional tests with one GHC version.
# GHC 8.8.2 for now to avoid https://gitlab.haskell.org/ghc/ghc/issues/17926.
#
# Runs: periodically on master, and on notable push to ci-windows.
