/*
* NAME
* yacc - how to use yacc
*
* DESCRIPTION
* This cookbook describes how to use yacc.
*
* You will have to add "-d" to the [yacc_flags] variable
* if you want %.h files generated.
*
* If a y.output file is constructed, it will be moved to %.list
*
* RECIPES
* %.c %.h: %.y applied if -d in [yacc_flags]
* %.c: %.y applied if -d not in [yacc_flags]
*
* VARIABLES
* yacc_src Yacc source files in the current directory.
* dot_src Source files constructable in the current directory
* (unioned with existing setting, if necessary).
* dot_obj Object files constructable in the current directory
* (unioned with existing setting, if necessary).
* dot_clean Files which may be removed from the current directory
* in a clean target.
* dot_lint_obj Lint object files constructable in the current directory
* (unioned with existing setting, if necessary).
*
* MANIFEST: cookbook for using yacc
* Copyright (C) 2007 Peter Miller
