+# compare-standalone-to-monorepo.sh
+#
+# Compare POM, Java source, and Java properties files between the
+# standalone copilot-sdk-java repo and the monorepo's java/ directory.
+#
+# Usage:
+#   ./scripts/compare-standalone-to-monorepo.sh /path/to/standalone /path/to/monorepo [--diff]
+#
+# The standalone path should point to the root of copilot-sdk-java.
+# The monorepo path should point to the root of copilot-sdk (the java/ subdir
+# is appended automatically).
+#
+# Compatible with macOS zsh and POSIX sh/bash.
