  -c, --max-crumbc	max number of crumbs\n\
  -C, --max-fragc	max number of fragments\n\
  -d, --max-deviance	max distance between file start and it's ideal position\n\
  -h, --help		you're looking at me !\n\
  -L, --no-locks	don't put a lock on written files\n\
  -m, --many-fs		shake subdirectories that are on different filesystems\n\
