+ * This is the main file used to add Cimarron graphics support to a software 
+ * project.  The main reason to have a single file include the other files
+ * is that it centralizes the location of the compiler options.  This file
+ * should be tuned for a specific implementation, and then modified as needed
+ * for new Cimarron releases.  The releases.txt file indicates any updates to
+ * this main file, such as a new definition for a new hardware platform. 
+ *
+ * In other words, this file should be copied from the Cimarron source files
+ * once when a software project starts, and then maintained as necessary.  
+ * It should not be recopied with new versions of Cimarron unless the 
+ * developer is willing to tune the file again for the specific project.
