+# Build QuickJS-backed puerts.dll for Windows x64 with a custom JS stack size.
+#
+# Usage:
+#   ./build_quickjs_win.sh [stack_size_in_bytes]
+#
+# Examples:
+#   ./build_quickjs_win.sh            # 2MB (default)
+#   ./build_quickjs_win.sh 4194304    # 4MB
+#   ./build_quickjs_win.sh 1048576    # 1MB
+#
+# Prerequisites:
+#   - Node.js (v16+)
+#   - CMake (v3.15+)
+#   - Visual Studio 2019 or 2022 with C++ Desktop workload
+#
+# The script clones PuerTS, patches the QuickJS default max stack size,
+# builds for Windows x64, and copies the resulting puerts.dll into
+# Puerts/Plugins/x86_64/.
