Adobe Frame Maker Equivalent for Linux?

Sim asks: "I currently work for a company which has used Frame Maker on SGI/IRIX systems for almost 10 years (meaning they have roughly 10 years worth of FM documents/reports/technical narratives/etc). It appeared that there would be a clean sweep of old SGI's out the door in favor of PC's running Linux, until a very nasty glitch got in the way: Adobe discontinued it's work on a Linux version of Frame Maker -- leaving the project in a beta format. The unstable format of the current Frame Maker version makes putting it into a production environment nearly impossible. I was hoping someone out there might know of a really powerful Frame Maker substitute."

"This substitute would need to have the following features:

• 'user friendly' GUI
• should be able to handle document management (with document cross refrencing links)
• graphics support
• import tables/create table
• handle multiple template styles (a style manager for creating templates would be wonderful)
• should be able to import/open .DOC formats as well as export/save to .DOC
• STABILITY

I've done some research on Star Office, as well as programs provided with a standard Red Hat install (koffice), both suites appear to be fairly unstable, and fairly buggy still. I've also researched LyX, but LyX doesn't have all the features I'm looking for. I'm open to any suggestions of a suitable Frame Maker substitute. I am willing to pay for the software -- just because I'd like it to run on Linux doesn't mean I expect it to be free."
