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.
u2spewfoo -V (return code: 255)
new_iterator: Failed to open file: --version
Errno: No such file or directory
u2dump: Failed to create new iterator with file: --version
u2spewfoo (return code: 1)
usage: u2eventdump <file>
