Hide incremental slides

Thanks very much for remark.js: I use it extensively when preparing lecture material for courses that I teach (see, e.g., http://www.engr.mun.ca/~anderson/teaching/3891/lecture).

I like to use incremental builds in the classroom, but when I distribute PDF versions of the lecture notes (slides + presenter notes with CSS to turn key words into blank spaces for students to fill in) I don't want to show all of the incremental steps. My current workflow requires me to manually go through the PDF output from Chrome's "Print to PDF" and delete all of the intermediate pages. This is a labour-intensive, slightly error-prone process. It would be really handy if I could run remark in a mode that only showed the final version of each complete (non-incremental) slide.
