x11-wm/i3-gaps doesn't install any man pages (as opposed to x11-wm/i3). Please consider installing man pages by default. x11-wm/i3 uses the `doman man/*.1` command in the ebuild since i3 unfortunately doesn't provide a "make install" target. And it doesn't look like it will be added in the near future: https://github.com/i3/i3/issues/1491
