Is there a way to get a double barline at the end of your SCAMP composition?
Not ignoring this question, BTW — just working on it! It seems that this was an oversight. You’re looking for it in abjad/lilypond, right?
Yes, I should have specified in the Lilypond (really PDF) output
I found it in the abjad docs for the Part demo as apply_final_bar_lines but unsure where to stick that in the grand scheme of things
