See groff(1)'s -V option to better understand what's happening.  In a
way, groff just obscures the workings for convenience, and I'm not sure
that's a good idea.  It may be better to avoid it and use the underlying
commands whilst you're learning.

    $ groff -V /dev/null
    troff -Tps /dev/null | grops
    $ groff -V -R /dev/null
    refer /dev/null | troff -Tps | grops
