+Getting Started:
+
+You can try out xscreensaver like so:
+
+       xscreensaver &
+       xscreensaver-command -demo
+
+After a few seconds, the screen should go black, and a dialog box should
+appear in the upper right corner.  This is "Demo Mode".
+
+Note: unlike `xlock', xscreensaver has a client-server model: the
+`xscreensaver' process is a daemon that runs in the background; it is
+controlled by the foreground `xscreensaver-command' program.
+
+xscreensaver has an extensive manual -- please read it!

                               ============
 
 The xscreensaver program waits until the keyboard and mouse have been idle
 for a period, and then runs a graphics demo chosen at random.  It turns off
 as soon as there is any mouse or keyboard activity.

+Changes since 2.20:   * Made "xscreensaver-command -time" use different words.

+                       since..."  and "screen non-blanked since..." instead of

+                       of people interpreted as meaning the opposite of what
+                       was intended.)
+                     * Improved some error messages, in the hopes of making
+                       the distinction between the xscreensaver and
+                       xscreensaver-command programs more obvious.
+                     * Rewrote (and reorganized) parts of the xscreensaver and
+                       xscreensaver-command manual pages.
+                     * Renamed xscreensaver's "-lock" command-line option to
+                       be "-lock-mode", to avoid confusion with the "-lock"
+                       option to xscreensaver-command, which does a totally
