2. Try adding shell completions for your program, so users can tab-complete options. This is particularly helpful in shells like Zsh that support help-text in tab completions, especially when combined with plugins like fzf-tab that enable fuzzy-searching help-text (see "code snippet 2")

3. Related to no. 2: use a well-understood format for "-h" and "--help" output. This makes auto-generating shell completions much easier. Alternatively, delegate the generation of both to a library that follows this advice.
3. Related to no. 2: use a well-understood format for "-h" and "--help" output. This makes auto-generating shell completions much easier. A great example is the Busybox coreutils' help output: it is much more concise than manpages, but descriptive enough to serve as a quick reference. Alternatively, delegate the generation of both to a library that follows this advice.
4. Ensure that the "whatis" and "apropos" commands work as intended after installing your man pages. These commands parse the beginnings of man pages to give one-line summaries of programs, and often power advanced tab-completion setups.
