+# yyacc - yacc wrapper
+#
+# Allows tokens to be written as `literal` and then automatically 
+# substituted with #defined tokens.
+#
+# Usage:
+#	yyacc file.y filetab.h file.yy 
+#
+# inputs:
+#	file.yy		yacc grammar with ` literals
+#
+# outputs:
+#	file.y		yacc grammar
+#	filetab.h	array of string <-> token mappings
+#
+# 03-13-93 - Documented and p moved in sed command (for some reason, 
+#	     s/x/y/p doesn't work).
+# 10-12-93 - Take basename as second argument.
+# 12-31-96 - reversed order of args to be compatible with GenFile rule
+# 03/19/02 (seiwald) - suffix symbols with _t to avoid conflicts
