Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
xfs_quota -VERSION (return code: 0)
xfs_quota version 4.3.0
xfs_quota --help (return code: 1)
xfs_quota: invalid option -- '-'
Usage: xfs_quota [-V] [-x] [-p prog] [-c cmd]... [-d project]... [path]
