+.SH GETTING STARTED
+For the impatient, try this:
+.EX
+ xscreensaver &
+ xscreensaver-command -demo
+.EE
+After a few seconds, the screen should go black, and a dialog box should
+appear in the upper right corner. This is \fIDemo Mode\fP.
+.SH DEMO MODE
+If \fIxscreensaver\fP receives the \fBDEMO\fP ClientMessage, which is done
+by running the
+.BR xscreensaver\-command (1)
+program with the \fB\-demo\fP option, the screensaver will black the screen
+and pop up a dialog box from which you can examine and experiment with the
+client programs.
+
+The dialog box contains a scrolling list, a text field, and a number of
+buttons.
+
+Double-clicking on one of the programs in the list will run it. The dialog
+box will disappear, allowing the program access to the full screen. Clicking
+the mouse again will bring the dialog box back.
+
+Single-clicking in the list will place the indicated program and its args
+in the text field to be edited. Edit the arguments and hit return to run
+the program with the parameters you have specified. (Note that these are
+one-time changes and won't be remembered; to make the changes permanent,
+you need to edit your X resource file.)
+
+The buttons are:
+.TP 8
+.B Run Next
+Clicking this button will run the next program in the list after the
+currently-selected one, and will scroll around to the top when it reaches
+the bottom.
+.TP 8
+.B Run Previous
+Opposite of Run Next; at the top, it scrolls around to the bottom.
+.TP 8
+.B Edit Parameters
+This pops up a second dialog box, in which you have the option to
+interactively change most of the screensaver's operational parameters,
+such as its timeouts, and whether it should lock the screen. Changing
+these parameters here will affect only the running \fIxscreensaver\fP
+process; to make the changes permanent, you need to edit your X resource
+file. (See below.)
+.TP 8
+.B Exit Demo Mode
+Returns to normal screensaver operation.
+.TP 8
+.B Reinitialize
+This causes the X resource database to be re-read, to pick up any changes
+you might have made. This works by causing the screensaver process to exit
+and then restart itself with the same command-line arguments. This is just
+like the \fI\-restart\fP argument to
+.BR xscreensaver\-command (1)
+except that when executed from this button, the screensaver will
+automatically return to demo mode after restarting.
