-# 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
-#
-# 3-13-93
-# 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
-# 11-20-2002
-# Reimplemented as a C program for portability. (Rene Rivera)
