        Unfortunately, this wouldn't affect xman, which doesn't know about
    man.conf and always use hardcoded commandline:
    
        viper:~% strings `which xman` | grep -i roff
        | geqn | gtbl | groff -Tascii -mandoc
    
        This is defined as `FORMAT' macro in xman/vendor.h (and slightly
    modified with x11r6-contrib-3.1.2-mandoc.patch in RedHat rpm), and can't be
    customized with environment/resources.
    
        There are many other help/manpage browsers (helptool, gnome-help-browser
    come to mind), so the right thing is to modify groff.
