如何不运行qtopia，只运行qt4.7环境？

我在某个官方文档上看到过一回，但是回头在找就找不到了，能告诉我在那个文档上吗？

大概意思就是：如果要单独运行qt4.7,可以在rcS文件中怎么编辑一下

#! /bin/sh

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:
runlevel=S
prevlevel=N
umask 022
export PATH runlevel prevlevel

#
#    Trap CTRL-C &c only in this shell so we can interrupt subprocesses.
#
trap ":" INT QUIT TSTP
