DOC_CONTENTS="To use ibus, you should:
1. Get input engines from sunrise overlay.
Run \"emerge -s ibus-\" in your favorite terminal
for a list of packages we already have.

2. Setup ibus:
$ ibus-setup

3. Set the following in your user startup scripts
such as .xinitrc, .xsession or .xprofile:

export XMODIFIERS=\"@im=ibus\"
export GTK_IM_MODULE=\"ibus\"
export QT_IM_MODULE=\"xim\"
ibus-daemon -d -x
