Migrating font faces from xemacs to emacs

Hi,

I hope it's ok to ask here although it's basically a xemacs question.
We are trying to migrate our users from xemacs to emacs (on SuSE Linux),
and besides some other things, the font faces are very very different.

I wonder if it is possible to get the lisp code for the default font
faces of xemacs so that we could add them to .emacs.d for users who
want to keep the old ones. I can list the faces with "list-faces-display"
in xemacs which will show Face/Foreground/Background/Fontspec for all
the faces.

But is there a way to get this output in lisp format in which xemacs
stores them when I change sth. from the default, e.g.
   '(custom-comment-face ((((class grayscale color) (background light)) (:foreground "green" :background "gray85")))))

I guess that's the format I could use for .emacs.d, isn't it?

Many thanks!
cu,
Frank
