   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.
