I believe so, I generally use daan's because I find it easier to create good
layout in and i think it is strictly more powerful. I didn't try to hard
to match up the operators exactly between the two instances but I
probably should, as I didn't use the hughespj one much. it is likely I
can get them to produce the same results with some tweaking and I might
want to add a couple more forms of line break into the class.
