Seems that some entries are missing in the manual, for e.g,

yliu at K55VM-ubuntu:~/sheepdog$ sheepfs -h
Usage: sheepfs [OPTION]... MOUNTPOINT
Options:
  -a  --address           specify the sheep address (default: localhost)
  -d, --debug             enable debug output (implies -f)
  -f, --foreground        sheepfs run in the foreground
  -k, --pagecache         use local kernel's page cache to access volume
  -n  --noobjectcache     disable object cache of the attached volumes
  -p  --port              specify the sheep port (default: 7000)
  -h, --help              display this help and exit

but the manual:
OPTIONS
       -d, --debug
              enable debug output (implies -f)

       -f, --foreground
              sheepfs run in the foreground

       -k, --pagecache
              use local kernel's page cache to access volume

       -h, --help
              display this help and exit

Thanks,
