commit 112f0b9ca720b8f0da4d4a39153c16f55e3294e1
Author: Morten Linderud <morten@linderud.pw>
Date:   Sat Mar 12 15:53:51 2022

    meson: Include documentation
    
    Documentation was removed from the build system with the migration to
    meson. This implements the help2man generation which existed in the
    autoconf setup.
