/*
splash.c
Splash plugin for the Gentoo RC sytsem.
splashutils needs to be re-written to support our new system.
Until then, we provide this compatible module which calls the
legacy bash scripts which is nasty. And slow.
For any themes that use scripts, such as the live-cd theme,
they will have to source /sbin/splash-functions.sh themselves like so
if ! type splash >/dev/null 2>/dev/null ; then
. /sbin/splash-functions.sh
