$ sheep -w

will get a core dump. I am expecting to see the help message for '-w' like

Valid cache types are:

Object cache
  -w object[:option[,option[,...]]]
  OPTIONS:
    size=<size>                     specify a cache size for object cache
    directio=<on|off>               avoid using gateway page cache

Disk cache
  -w disk

Thanks,
Yuan
