Hi there. I have a problem and was wondering if anyone can help me out.
I am currently printing my dissertation. The document is formatted in LaTeX,
with postscript output produced by "dvitps". So far, so good. Now the problems.

First, the dissertation has to be on A5 paper (half the size of A4). What I've
done (from LaTeX) is to produce output that fits onto A5 paper with appropriate
margins. This means that left-hand pages look like:

+-------+
|    ** |
|    ** |
|       |
|       |
+-------+

while right-hand side pages look like:

+-------+
|**     |
|**     |
|       |
|       |
+-------+

This allows me, with the aid of a double-sided photocopier, to do double-
sided copying such that the text folds onto itself. This was all well and
good, but wastes half the paper! In addition, the printer says that the
best way for him to bind is if I produce a sheet with 4 "pages" on it.
One side should have the fourth page (left side) and first page (right side)
while the other side should have the second (left side) and third (right side).
Now, I can do this using the photocopier from the printed form I have right now,
however, it seems to me that it would save time and paper if I could massage the
PostScript file to take every four pages, and produce 4/1 and 2/3 appropriately:

A4 page on its side, with overlayed pages:


      +-+---------++---------+-+
      | | ******  ||  ****** | |
      | | ******  ||  ****** | |
      | | ******  ||  ****** |<--------- A4 page (seen side-ways)
      | | ******  ||  ****** | |
      | | ******  ||  ****** | |
      | +---------||---------+ |
      |           ||           |
      |           ||           |
      |           ||           |
      +-----------++-----------+      
	     ^           ^
             |           |
       pg. 4 or 2      pg. 1 or 3

So, briefly, can anyone give me an idea of (i) whether this can be done in 
PostScript, (ii) how to do it?

Thanks in advance, Afzal
