+ * features.h -- predefined symbols and &features
+ *
+ * This file consists entirely of a sequence of conditionalized calls
+ *  to the Feature() macro.  The macro is not defined here, but is
+ *  defined to different things by the the code that includes it.
+ *
+ * For the macro call  Feature(guard,symname,kwval)
+ * the parameters are:
+ *    guard	for the compiler's runtime system, an expression that must
+ *		evaluate as true for the feature to be included in &features
+ *    symname	predefined name in the preprocessor; "" if none
+ *    kwval	value produced by the &features keyword; 0 if none
+ *
+ * The translator and compiler modify this list of predefined symbols
+ * through calls to ppdef().
