+\section1 The QQmlExpression Class
+
+The QQmlExpression class provides a way for clients to evaluate JavaScript
+expressions from C++, using a particular QML evaluation context.  This allows
+clients to access QML objects by id, for example.  The result of evaluation
+is returned as a QVariant, and the conversion rules are defined by the QML
+engine.
