Hi Craig,

Interesting.. One of the lesser known features of Ghostscript.So of
course, I had to try it :)

My completely unscientific testing:

Any Scribus PDF which has presentation effects, Javascript, Form Buttons
or Fields causes gs to die an ugly death. This is quite common in my
experience.

Random sampling of PDF's from Scribus which are a mixture of text and
images:

Original:	After pdfopt:
96kb		187kb
111kb		213kb
80kb		214.6kb	

This is consistent with my experience with recent Scribus PDF and
Acrobat 5.0.5. The file size is larger after linearization. 

I have not tried it yet with Acrobat 6.0, as Acrobat 6.0 does not have
parsing issues with Scribus PDF's like 5.0.5. 

I discovered this workaround to get Acrobat 5.0.5/Pit Stop 5.04 to read
Scribus PDF's. Just open in Acrobat and resave with linearization
enabled. Then Acro 5.0.5 and Pit Stop are happy. I think it is a bug in
5.0.5, as Markzware Flight Check Pro, Indesign nor Illy 10 have any
problems with Scribus PDF's. Illy 10 imports Scribus PDF's without a
problem and all objects are fully editable.

Peter
