[reportlab-users] ANN: pdfnup 0.3.0

[Luc Saffre]

Dinu,

here is a next bug report, consider it as a Christmas gift ;-)

Now I tested it on a similar file, created using pdflatex. The .tex
input file is here:

  http://lino.saffre-rumma.ee/dl/pdfnup_test.tex

and the resulting pdf is here:

  http://lino.saffre-rumma.ee/dl/pdfnup_test.pdf

And here is the traceback I get when I try pdfnup_test.py on it:

C:\temp>python pdfnup_test.py pdfnup_test.pdf
Traceback (most recent call last):
