Quicktip: Setting keyboard layout in GNOME via CLI

Since I tend to break my installation quite often while testing new stuff, I'm always looking for more agile way of re-setting my system quicky. Of course backups could do the job, but I find a clean install much cleaner and safer for my purposes.
So, here is a tip how to set keyboard layouts from the command line using GNOME - very useful if  you speak more than one language:

gconftool-2  -R /desktop/gnome/peripherals/keyboard/kbd
gconftool-2 --recursive-unset /desktop/gnome/peripherals/keyboard/kbd
gconftool-2 -s /desktop/gnome/peripherals/keyboard/kbd/layouts -t list \
--list-type=string [us,de]
gconftool-2 -s /desktop/gnome/peripherals/keyboard/kbd/options -t list \
 --list-type=string ["grp	grp:alt_shift_toggle,terminate	terminate:ctrl_alt_bksp"]

Do notice: there are TABS in the empty spaces up there. GNOME's xml was intolerant for my attempts to replace them with spaces, and really only worked with the braces.
