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. |
