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.
Report bugs to <bug-automake@gnu.org>.
