+# Usage:
+#   Call this script from debian/rules, before dh_gencontrol is run,
+#   to get all needed variables computed in debian/$p.substvars for
+#   each package $p found through dh_listpackages.
+#   .
+#   This script has support for udebs.
+set -e
+
+# Sanity check. All drivers build-depend on debhelper:
+if ! which dh_listpackages >/dev/null 2>&1; then
+  echo "E: dh_listpackages not found, debhelper package missing?"
+  exit 1
