I did this and put lines like this in my document:

    @CD @Monochrome @Case {
    Yes @Yield @IncludeGraphic{"images/quadratic2-linux-bw.eps.gz"}
    else @Yield @IncludeGraphic{"images/quadratic2-linux.eps.gz"}
    }

This gave no error messages but didn't work reliably.

So I changed them to this:

    @CD @Monochrome @Case {
    Yes @Yield @IncludeGraphic{"images/quadratic2-linux-bw.eps.gz"}
    No @Yield @IncludeGraphic{"images/quadratic2-linux.eps.gz"}
    }

This seems to work reliably but outputs some strange error messages (but
only in the --'@Monochrome{Yes}' case:

    replacing unknown @Case option ?? by Yes

Anyway, it works, so that you very much:-)
