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