program, which is what actually does the work.)
.TP 4
-.B Verbose Diagnostics
-Whether to print lots of debugging information.
+.B Text Manipulation
+Some of the display modes display and manipulate text. The following
+options control how that text is generated. (These parameters control
+the behavior of the
+.BR xscreensaver\-text (1)
+program, which is what actually does the work.)
.TP 4
-.B Display Subprocess Errors
-If this is set, then if one of the graphics demos prints something to
-stdout or stderr, it will show up on the screen immediately (instead of
-being lost in a hidden terminal or file that you can't see.)
-
-If you change this option, it will only take effect the next time the
-xscreensaver daemon is restarted. (All other settings take effect
-immediately.)
+.B Host Name and Time
+If this checkbox is selected, then the text used by the screen savers
+will be the local host name, date, time, and system load.
.TP 4
-.B Display Splash Screen at Startup
-Normally when xscreensaver starts up, it briefly displays a splash dialog
-showing the version number, a \fIHelp\fP button, etc. If this option is
-turned off, the splash screen will not be shown at all.
+.B Text
+If this checkbox is selected, then the literal text typed in the
+field to its right will be used. If it contains % escape sequences,
+they will be expanded as per
+.BR strftime (2).
+.TP 4
+.B Text File
+If this checkbox is selected, then the contents of the corresponding
+file will be displayed.
+.TP 4
+.B Program
+If this checkbox is selected, then the given program will be run,
+and its output will be displayed.
+.TP 4
+.B URL
+If this checkbox is selected, then the given HTTP URL will be downloaded
+and displayed repeatedly. If the document contains HTML, RSS, or Atom,
+it will be converted to plain-text first.
+
+Note: this re-downloads the document every time the screen saver
+runs out of text! It might be considered abusive for you to point
+this at a web server that you do not control, as it will probably
+be hitting that server multiple times a minute.
.TP 4
.B Power Management Enabled
Whether the monitor should be powered down after a period of inactivity.
power down after this much idle time. This duration should be greater
than or equal to \fISuspend\fP.
.TP 4
-.B Install Colormap
-On 8-bit screens, whether to install a private colormap while the
-screensaver is active, so that the graphics hacks can get as many
-colors as possible. This does nothing if you are running in 16-bit
-or better.
-.TP 4
.B Fade To Black When Blanking
If selected, then when the screensaver activates, the current contents
of the screen will fade to black instead of simply winking out. (Note:

take.
