# TRIGGER: Runs on any push to binaries-windows-arm64 or binaries branches.
# ACTION: Builds, unit-tests and saves windows arm64 binaries with stack and the default ghc.
# XXX There's no windows ARM version of stack yet; the preinstalled stack,
# the one installed by ghcup, and the one installed by stack's installer are all x86_64.
# So currently this workflow just builds x86_64 hledger binaries, and is pointless.
