How to use "--multiple-output"

Hi,

I would like to know how to use "--multiple-output".

% env LC_ALL=C intltool-merge ../po gnome-cd.desktop.in gnome-cd.desktop \
  -d -u -p --multiple-output "es de"

Now I tries to separate all locales from the multilingual files; .desktop, .xml,
.schemas, .icon..., by locale likes .mo files.

How do you think?

I'm not in this alias, so please reply me directly.
Thanks,
fujiwara
