DOCBOOK: DocBook -> ps anyone?

[Alex Povolotsky <tarkhil@doomstar.msk.port.ru>]

Hello!

I know I must have missed something, but I cannot make PostScript of 
my DocBook file :-(

I've tried to use jade, and it produced .tex, but running tex result in the
following error:

This is TeX, Version 3.14159 (Web2C 7.3.1) (format=tex 2000.2.24)  2 MAR
2000 13
:28
**filesys.tex
(filesys.tex
! Undefined control sequence.
l.1 \FOT
        {2}\Seq%

What should I do to set everything properly? 

I've tried also sgmlfmt, but it formats html poorly, and I still have
troubles making groff understanding Russian, but it's quite different
story...

Alex.
