    <title>Introduction to XScreenSaver</title>

    <para>The <application>XScreenSaver</application> is a modular screen
    saver and locker for the X Window System. It is highly customizable and
    allows the use of any program that can draw on the root window as a
    display mode. The purpose of <application>XScreenSaver</application> is
    to display pretty pictures on your screen when it is not in use, in
    keeping with the philosophy that unattended monitors should always be
    doing something interesting, just like they do in the movies. However,
    <application>XScreenSaver</application> can also be used as a screen
    locker, to prevent others from using your terminal while you are
    away.</para>

    where to put all the files if <application>GNOME</application> is installed.
    To get around this, run the following command and see an optional configure
    switch described later below.</para>

<screen><userinput>sed -i -e "s,@GNOME_DATADIR@,$GNOME_PREFIX/share," driver/Makefile.in</userinput></screen>
