Reduce the size of Scribus generated PDFs

Simply using Ghostscript
For example, on a MacIntosh with Mac OS 10.6.2, Scribus 1.3.6, Ghostscript 8.71, this ghostscript command will knock a 1.9GB PDF file generated by Scribus down to less than 300MB which is very helpful :

gs-8.71-macosx -dPDFSETTINGS=/prepress -dSAFER -dCompatibilityLevel=1.5 -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sstdout=%stderr -dGrayImageResolution=600 -dMonoImageResolution=1200 -dColorImageResolution=300 -sOutputFile=vol_iv_gs.pdf -c .setpdfwrite -f vol_iv.pdf

Using a Python Script
A linux only program. Note: Not all PDFs can be reduced, sometimes they are even larger! Script creates a back up of the original (filename.pdf.orig) as well as the new file (filename.new.pdf and you require pdftops and ps2pdf14


 * 1) ! /usr/bin/env python
 * 2) -*- coding: utf-8 -*-
