[NTG-context] on luatex.wrapup

Hi Hans, I would like to use luatex.wrapup to remove media files that I don’t need anymore once the PDF document is generated. I have realized that luatex.wrapup works at the very end of the PDF generation, but in each run. Is there no way to have a luatex.final_wrapup, when no other run will take place? Many thanks for your help, Pablo -- http://www.ousia.tk
