CAD Publisher (Autoset), out of Australia, offers equivalent capability.
Their web site was at: http://www.jwgraphics.com.au

UPDATE (28 December 2009) : This site is now gone, replaced by a parasitic link farm. I have to guess that CAD Publisher is also no longer available.

John Walker is (was?) the head of the firm.
His last email was walkerjr@jwgraphics.com.au - you might give it a try.
Their last phone number in Melbourne, Australia was 613 9879 4388 (from the US: 011 613 9879 4388)

NOTE: Perhaps the same technology changes also eventually made CAD Publisher obsolete. AutoScript was a niche product which was being eclipsed by advances in tech and there was no way we could keep up with the changes. Too many people would have to have been added to staff and the niche of rendering was already being eaten up by the product itself. So when AutoScript closed up (September 1998) it was really a matter of time before what AutoScript did in providing PostScript fonts, shading and output would be overtaken by other methods to acheive the same result. All in all AutoScript lasted about 11 years (from 1987) which in the changing world of software is a long time and in the conditional-love world of niches to fill is a very long time especially for a niche which has enough main-stream demand that niche opening would soon be filled by the people who, themselves, left it open.
