45
46 Wrapper for lex/yacc invocations, renaming files as desired.
47
48 INPUT is the input file
49 OUTPUT is one file PROG generates
50 DESIRED is the file we actually want instead of OUTPUT
51 PROGRAM is program to run
52 ARGS are passed to PROG
53
54 Any number of OUTPUT,DESIRED pairs may be used.
