[Groff] groff to RTF or Word

[Doug McIlroy]

I have a paper composed in notrivial groff (uses pic,
eqn, tbl, and .PSPIC), which I'd like to submit to a
journal that takes any kind of digital text--as
long as it's Word or RTF.  I haven't been able to find
any tool that offers much help in getting from here to 
there. I'd be delighted if somebody could tell me I 
missed something capable.
