Yes.

For icewm-gnome:

--------------------------

preinst:

case "$1" in
    install|upgrade)
        if [ -n "$2" ] && dpkg --compare-versions "$2" lt "1.0.8.6-1"
        then
            if [ -d /usr/share/doc/icewm-gnome ]; then
                mv /usr/share/doc/icewm-gnome \
                /usr/share/doc/icewm-gnome.moved-by-preinst
            fi
        fi
    ;;
esac


postinst:


if [ "$1" = "configure" ]; then
    rm -rf /usr/share/doc/icewm-gnome.moved-by-preinst
fi


postrm:

case $1 in
    abort-install|abort-upgrade)
        if [ -d /usr/share/doc/icewm-gnome.moved-by-preinst ]; then
            mv /usr/share/doc/icewm-gnome.moved-by-preinst \
               /usr/share/doc/icewm-gnome
        fi
        ;;
esac

-----------------

I didn't find the trick myself. It comes from groff.
