Incidentally, man --help on my machine shows "-k, --apropos equivalent to apropos", which isn't very useful. I know the two are equivalent, because they're on the same line of switches, what does it actually do?
With some further man digging, apropos is actually a separate program that looks through man page names/descriptions for the argument. Unless you run it with no arguments, in which case it just outputs "apropos what?" Instead of an actual error message like "No search term provided" or something

That's your hint to execute either 'man apropos' or 'man man'. Both tell you in detail what the flag and utility do.
You seem likely to be very disappointed in the '-h'/'-H' output of utilities from the BSD tradition. The output is often a list of all of the (almost always exclusively short) options presented as a sea of characters... and nothing else.
