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.
