  --threads <number>	Limit the maximum number of tasks allowed to process concurrently (Set to 0 for unlimited.)
  -M			Set number of parallel running tasks to unlimited. (Same as `--threads 0`). (default).
  -m			Limit number of parallel tasks to the number of active CPU processors.
+ -q			Quiet mode. Don't output info messages about successful `stat`ing.
  --save <file>		Dump the collected data to this file for further inspection (only available when compiled with feature `inspect`)

 NOTES:
  The first time a non-option argument is encountered, the program stops parsing arguments and assumes the rest of the arguments are paths.
  If parallelism is set to unlimited, there can be a huge syscall overhead. It is recommended to use `-m`.

+ Symlinks are ignored while collection stat data. They will fail with message 'Unknown file type'. Symlinks are generally very small in the actual data they contain themselves, so this is *usually* unimportant.
