[luatex] Is there a hook that could be used by a pdf postprocessor?

[David Shourabi Porcel]

Hi!

If it's possible to carry out the postprocessing you need from within
LuaTeX instead of with ghostscript, the callback finish_pdffile might
be an option. Otherwise, you're better off with a build system like
Make.
