+/**
+ * \def DEBUG_LEVEL
+ *
+ * Controls the level of assertion checking.
+ *
+ * The higher the debug level, the more assertions will be compiled
+ * in.  This increases the amount of debugging information, but slows
+ * down (and increases the size of) the binary.
+ *
+ * The debug levels, from lowest to highest, are DEBUG_NONE,
+ * DEBUG_FAULT, and DEBUG_ALL.  The default level is DEBUG_ALL.
