simple tool for slicing pages out of pdfs to new pdfs
create a pages.csv with page numbers on lines, 1 per line edit variables at the top of Makefile as required make
an example of this as a single loop is in as_loop.tex. if the splits are very large this may be necessary.
parameters are controlled in spec.json in particular this is where you control landscape vs portrait
this depends on two files: a csv with 2 columns: filenme, page. default spec.csv a json with the header setup spec. default spec.json
