Michele — Yes.
I find the ConvertLIT GUI easier and better to use than clit but, of course, I aint posting a link here. You should find it if you search in Google. It's the DukeLupus one.
ABC Lit converter - which is also free - don't do a very good conversion in my opinion. It needs too much editing on the resultant file.
Also, as others have said - BookDesigner 4 will also do this for you but I haven't got around to trying this yet.
