[plt-scheme] fill-paragraph (M-q) analog in DrScheme?

Hello all,

This question has been puzzling me for a while: is there an analog of  
Emacs' fill-paragraph (M-q) command in DrScheme?  I know about  
turning on line wrapping, but it's nice to automatically have the  
program insert newlines in long comment sections, etc, particularly  
if there are other people who might read your code in Emacs.

I'm sorry if the answer to this question should have been obvious :).

Thanks,
Will
