+\n\
+ This program provides external control of a running xscreensaver process.\n\
+ Version %s, copyright (c) 1991-1997 Jamie Zawinski <jwz@netscape.com>.\n\
+\n\
+ The xscreensaver program is a daemon that runs in the background.\n\
+ You control a running xscreensaver process by sending it messages\n\
+ with this program, xscreensaver-command. See the man pages for\n\
+ details. These are the arguments understood by xscreensaver-command:\n\
+\n\
+ -demo Ask the xscreensaver process to enter interactive demo mode.\n\
+\n\
+ -activate Turn on the screensaver (blank the screen), as if the user\n\
+ had been idle for long enough.\n\
+\n\
+ -deactivate Turns off the screensaver (un-blank the screen), as if user\n\
+ activity had been detected.\n\
+\n\
+ -cycle If the screensaver is active (the screen is blanked), then\n\
+ stop the current graphics demo and run a new one (chosen\n\
+ randomly.)\n\
+\n\
+ -next Like either -activate or -cycle, depending on which is more\n\
+ appropriate, except that the graphics hack that will be run\n\
+ is the next one in the list, instead of a randomly-chosen\n\
+ one. In other words, repeatedly executing -next will cause\n\
+ the xscreensaver process to invoke each graphics demo\n\
+ sequentially. (Though using the -demo option is probably\n\
+ an easier way to accomplish that.)\n\
+\n\
+ -prev Like -next, but goes in the other direction.\n\
+\n\
+ -exit Causes the xscreensaver process to exit gracefully. This is\n\
+ roughly the same as killing the process with `kill', but it\n\
+ is easier, since you don't need to first figure out the pid.\n\
+ (Note that one must *never* kill xscreensaver with -9!)\n\
+\n\
+ -restart Causes the screensaver process to exit and then restart with\n\
+ the same command line arguments as last time. Do this after\n\
+ you've changed your X resource settings, to cause\n\
+ xscreensaver to notice the changes.\n\
+\n\
+ -lock Tells the running xscreensaver process to lock the screen\n\
+ immediately. This is like -activate, but forces locking as\n\
+ well, even if locking is not the default.\n\
+\n\
+ -version Prints the version of xscreensaver that is currently running\n\
+ on the display -- that is, the actual version number of the\n\
+ running xscreensaver background process, rather than the\n\
+ version number of xscreensaver-command.\n\
+\n\
+ -time Prints the time at which the screensaver last activated or\n\
+ deactivated (roughly, how long the user has been idle or\n\
+ non-idle -- but not quite, since it only tells you when the\n\
+ screen became blanked or un-blanked.)\n\
+\n\
+ See the man page for more details.\n\
