This repository is nothing more than a Makefile that sets up a build environment for ToaruOS's man stack (man, roff, more) for host systems. Check out the repo next to your toaruos checkout, run make prep to create symlinks, then run make to build, and make install to install to ~/bin.

The resulting binaries are prefixed with toaru- and will search for manual pages in ../toaruos/base/usr/share/man relative to where the repo was built.

Generally, toaru-man some-manual-page should suffice after that to view ToaruOS's manuals, but if the ToaruOS more proves insufficient you can try something like toaru-roff $(toaru-man -w some-manual-page) | less -R instead, or if you want to see how a manual page renders in the host's tooling, you can try something like man $(toaru-man -w some-manual-page).
