During an OpenSSL usability study we found out that many participants (more than a quarter) intuitively expected to find manual pages under man openssl subcommand (e.q. man openssl verify) instead of man subcommand (e.g. man verify). The experiment ran on Ubuntu 16.04.

This could be easily solved by symlinking the manual pages.
(This is already used elsewhere -- for example man git commit automatically redirects to man git-commit on Fedora.)

Although this is mostly a thing of the ports to the individual operating systems, the upstream project can probably ease the setting (as suggested by @richsalz).
