+# Helper script to generate package which
+# can enable debug verbose message in maintainer scripts.
+# It helps to trace internal behavior install/upgrade/remove
+# and so on.
+#
+# Usage: debug-package-converter.sh [debug] PATH_TO_DEB_OR_RPM
+#
+# e.g.
+# $ debug-package-converter.sh debug fluent-package-6.0.0-1.el8.x86_64.rpm
+# $ debug-package-converter.sh debug fluent-package_6.0.0-1_amd64.deb
+#
+# It repack to fluent-package-6.0.0-2.el8.x86_64.rpm or
+# fluent-package_6.0.0-2_amd64.deb.
