unfortunately there's a trend lately where many newer cli tools don't have a man page. they put up a --help and think it suffices
even though there are tools to automatically generate man pages those days
I agree. If it can be launched from the command line, it deserves a man page.
Because installing a man page requires root and a writeable root fs for that matter
I should write a tool that converts help output to troff, even if the result wouldn't be as detailed and nice to read as a good man page it would save me the frustration of having to stab at "will i get usage docs with a -h, a --help, a -help, or running it with no args at all".
