+# We cache thinned versions of universal ("fat") Qt binaries to reduce the size of the packages and caches.
+# The universal binaries are install via aqtinstall. We use wildcards to get the latest patch version. E.g. "6.6.*" -> "6.6.3".
+# This script is used to resolve the latest patch version of Qt.
+
+# This script is meant to be used by the ci enironment on macos runners only.
+# It uses the runner's GITHUB_OUTPUT env variable.
+
+# Usage example: .ci/resolve_latest_aqt_qt_version.sh "6.6.*"
