+    \title Export Item
+    \brief Exports dependencies and properties to other products.
+
+    An \c Export item can appear inside a \l{Product Item}. It defines a Module with the product's
+    name that can be depended on by other products.
+    The properties attached to the Export item will take effect in all products that depend on the
+    product inside which the Export item is defined.
+    As an example, consider these two products:
+    \code
+    Product {
+        name: "A"
+        Export {
+            Depends { name: "cpp" }
+            cpp.includePaths: product.sourceDirectory
+            cpp.defines: ["USING_" + product.name.toUpperCase()]
+        }
+    }
+
+    Product {
+        name: "B"
+        Depends { name: "A" }
+    }
+    \endcode
+
+    The sources in product B will be able to use headers from product A without specifiying
+    the full path to them, because the include path has been made known to the compiler via
+    A's Export item. Additionally, product B will be compiled with the define \c{USING_A}.
+
+    \note This relationship is transitive, so a product C depending on product B will also
+    get the include paths and preprocessor macros via A's Export item.
+
+    In contrast to Module items, \c{product} within Export items refers to the product which defines
+    the Export item. Use the \c{importingProduct} variable to refer to the product that
+    pulls in the resulting module.
