+// This JavaScript file is run under Windows Script Host from the Visual Studio build.
+// It creates .CPP files from JavaScript files and is intended to duplicate the functionality
+// of the jsToH Python function in SConstruct.  By using only standard Windows components
+// (Windows Script Host, JScript) we avoid the need for Visual Studio builders to install
+// Python, and we don't need to include the generated files in Git because they can be
+// recreated as required.
