🚀 go-pugleaf

I'm looking for a program that will print two half pages onto each
side of a full-sized page so that the resulting bundle can be folded
in the middle and be stapled down the spine to make a 5.5x8.5inch
brochure.  I remember hearing about such a program on sumex but was
unable to find it (called something like paperback maker).  Besides
reducing the pages to fit side-by-side, such a program needs to figure
out what page numbers need to be printed on the same physical page so
that the paging works out correct when it all is folded into a book,
and it needs to coordinate double-sided printing.  Any pointers to
such a program would be useful.

I took a look at dynopage, but it seems to handle two-sided loose-leaf
printing in terms of page placement, but not folios (where, for
example, one piece of paper will have page N on the left and page 1 on
the right, and on the reverse will have page 2 on the left and page
N-1 on the right).  If there is some setting of dynopage that will do
this I would love to know.

thanks for any pointers,
