+ * 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.
