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.
yppush --version (return code: 0)
yppush (ypserv) 2.19
yppush --help (return code: 0)
Usage:
yppush [-d domain] [-t timeout] [--parallel # | --port #] [-h host] [-v] mapname ...
yppush --version
