[lug] Gimp CMYK

[jd]

Hello,
  From looking on the web it appears that GIMP does not support
CMYK yet. So I was hoping someone could give me some input on
converting to CMYK using another program (Phototshop). Will
this make big chages to the picture?

Also, just in general is the GIMP recomened for projects
that will be printed..such as flyers and brochuers?

Are there any RGB to CMYK converters I can run on a image
that work for Linux? Perl or Python module maybe?..
couldnt find anything on CPAN.

Thanks,
jd
