47    
48     Wrapper for lex/yacc invocations, renaming files as desired.

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.
