46 Usage: ylwrap [--help|--version] INPUT [OUTPUT DESIRED]... -- PROGRAM [ARGS]... | |
47 | |
48 Wrapper for lex/yacc invocations, renaming files as desired. | |
49 | |
50 INPUT is the input file | |
51 OUTPUT is one file PROG generates | |
52 DESIRED is the file we actually want instead of OUTPUT | |
53 PROGRAM is program to run | |
54 ARGS are passed to PROG | |
55 | |
56 Any number of OUTPUT,DESIRED pairs may be used. | |
