+#!/usr/bin/env bash
+# Run an executable module by its CMake target name (as registered in
+# that module's own CMakeLists.txt), resolved via the manifest that
+# _write_module_manifest() generates at configure time -- so this script
+# never needs updating when modules are added, removed, or renamed.
+#
+# Usage (from the project root):
+#   scripts/run.sh <target-name> [-- program-args...]
+#
+# Examples:
+#   scripts/run.sh hello_exe
+#   scripts/run.sh farewell_exe -- Ale
