#!/bin/bash
#
# splash.sh - This shell script triggers bootsplash actions during
# system boot/shutdown. It can be run by the init scripts repeatedly
# specifying the currently executed system script.
# 
# This script is used to play animations/sounds/show text/move the
# progress bar, etc.
# 
# We call this function from /etc/rc.status:rc_splash() 
#
# This program is free software; you may redistribute it under 
# the terms of the GNU General Public License. This program has 
# absolutely no warranty.

#
# this script expects the following environment variables for an operable
# progress bar:
#
#  sscripts = number of start scripts to be executed for runlevel change
#  kscripts = number of stop scripts to be executed for runlevel change
#  progress = number of currently executed start/stop script
#  RUNLEVEL = runlevel to be reached.
#
# To play animations, it's advised that you have an animations.cfg in your
# theme's config directory specifying the initscript name for an event and
# the command to be executed:
#
#   fsck start:bootanim start bounce.mng
#   master:bootanim stop
#
# See http://www.bootsplash.org/ for more information.
