[Scribus] how to resize document?

[Jeremy C. Reed]

I can't find in the documentation nor via the scribus menus...

how do you resize a document?

I have a book cover which dimensions had to be changed.

I manually edited the XML in the sla file and changed the 
PAGEWITH value within the DOCUMENT tag.

Is that okay? It appears to work for me, but don't know if this is wrong 
normally.

Thanks again for scribus ... it is a lot easier for me than inkscape for 
making a book cover.
