rtf to doc?

[Linux for blind general discussion]

Hi,
A comparative question to the html one from the other day.
I can, and often do, generate rtf files in Wordperfect.
For a single instance though I desire converting the rtf file I am going 
to create into word, without having  direct access to the program, or 
windows either for that matter.
Is there a pro word like the anti one, or an option inunrtf that manages 
this?
Thanks,
Karen
