By cropping with -c and studying the results, define the areas of the input PDF's pages you want visible. Then, with--nup4, map those areas onto 4 input pages per 1 output page, arranged in such a way that double-sided print-out of those output pages can be cut, folded, and bound (helped by addition of stencils for small incisions to carry rubber bands or the like) into a small A6 book. Each unit of 8 pages from the input PDF is mapped by --nup4 onto two pages representing two sides of a (no-tumble-duplex-printed) A4 paper:

-To turn this paper into a small 8-pages book, first cut it into two A5 papers along its horizontal middle. Fold both A5's by their vertical middles, with pages 2-3 and 7-6 on the folds' insides. You now have two 4-page A6 "books" of pages 1-4 and pages 5-8. Fold both closed and (counter-intuitively) stack the second one on top of the first one (creating a temporary page order of 5,6,7,8,1,2,3,4). This reveals a small stencil on the top left of page 5 – cut it out, with all other pages folded and aligned under it, creating a small notch in the upper "inner" corner of all pages. Turn around the stack to find a mirror stencil on the bottom and repeat the cutting. Each page now has cuts on top and bottom of its inner margins into which a rubber band can be hooked, or through which a string may be looped and tied, to bind the page's inner margins into a kind of book spine. You may now swap the order of the 4-page books back into a proper final page order (of 1,2,3,4,5,6,7,8) and repeat the whole process for each further --nup4 output paper.

COMMAND EXAMPLES:
bookmaker.py -i INPUT.pdf --page_range 3-7 -o OUTPUT.pdf
Produce COMBINED.pdf from A.pdf's first 7 pages, B.pdf's pages except its first two, and all pages of C.pdf:
- bookmaker.py -i A.pdf -p start-7 -i B.pdf -p 3-end -i C.pdf -o COMBINED.pdf
+ bookmaker.py -i A.pdf -p start-6 -i B.pdf -p 2-end -i C.pdf -o COMBINED.pdf
Crop each page 5cm from the left, 10cm from the bottom, 2cm from the right, and 0cm from the top:
bookmaker.py -i INPUT.pdf -o OUTPUT.pdf --crops "5,10,2,0"
FURTHER NOTES:
-For arguments like -p, page numbers are assumed to start with 1 (not 0, which is treated as an invalid page number value).
+For arguments like -p, page numbers are assumed to start with 0 (i.e. first page at 0, second page at 1 …).
If -p defines a page range beyond the source document's last page, the remaining pages will be created blank.
