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.
nslookup -version (return code: 0)
nslookup 9.10.3-P4-Ubuntu
nslookup help (return code: 0)
Server: 10.0.2.3
Address: 10.0.2.3#53
