+ * \brief Hold extra data on a cmMakefile instance for a command.
+ *
+ * When CMake commands need to store extra information in a cmMakefile
+ * instance, but the information is not needed by the makefile generators,
+ * it can be held in a subclass of cmData.  The cmMakefile class has a map
+ * from std::string to cmData*.  On its destruction, it destroys all the
+ * extra data through the virtual destructor of cmData.
