Troff <-> FrameMaker conversion tool - anybody seen one?

[mtxinu!dopey!ramiro at ucbvax.berkeley.edu]

Hi netfolks, I'm desperately trying to avoid the painful process of
converting troff files to framemaker (talk about evolution!). I know some
less lazy and more enterprising hacker out has probably cooked up a tool
for this. If you know of one, could you please let me know how I could get
a copy? email is preferred.
