       bsod - Blue Screen of Death emulator

       bsod  [-display	host:display.screen]  [-foreground color] [-background
       color] [-window]	[-root]	[-mono]	[-install]  [-visual  visual]  [-delay
       seconds]	[-fps]

       The bsod	program	is the finest in personal computer emulation.

       bsod steps through a set	of screens, each one a recreation of a differ-
       ent failure mode	of an operating	system.	 Systems depicted include Win-
       dows  3.1,  Windows  95,	 Windows  NT, MS-DOS, AmigaDOS 1.3, Linux, SCO
       UNIX, BSD UNIX, HPUX, Solaris, Tru64, VMS, HVX/GCOS6, IBM OS/390, OS/2,
       MacOS  (MacsBug,	 Bomb,	Sad Mac, and OSX), Atari ST, Apple ][+,	VMware
       and NCD X Terminals.

       bsod accepts the	following options:

       -window Draw on a newly-created window.	This is	the default.

       -root   Draw on the root	window.

       -mono   If on a color display, pretend we're on a monochrome display.

	       Install a private colormap for the window.

       -visual visual
	       Specify which visual to use.  Legal values are the  name	 of  a
	       visual  class,  or the id number	(decimal or hex) of a specific

       -delay delay
	       The duration each crash-mode is displayed before	selecting  an-

       -only which
	       Tell it to run only one mode, e.g., -only HPUX.

       -fps    Display the current frame rate and CPU load.

       DISPLAY to get the default host and display number.

	       to  get	the  name of a resource	file that overrides the	global
	       resources stored	in the RESOURCE_MANAGER	property.

       Notable X resources supported  include  the  following,	which  control
       which  hacks are	displayed and which aren't.  doWindows,	doNT, doWin2K,
       doWin10,	 doRansomware,	doAmiga,  doMac,  doMac1,  doMacsBug,  doMacX,
       doSCO,  doAtari,	 doBSD,	doLinux, doSparcLinux, doHPPALinux, doBlitDam-
       age, doSolaris, doHPUX, doApple2,  doOS390,  doTru64,  doVMS,  doMSDOS,
       doOS2,  doHVX,  doVMware,  and  doATM.	Each of	these is a Boolean re-
       source, they all	default	to true, except	for  doAtari,  doBSD,  doSpar-
       cLinux,	and  doHPPALinux,  which  are  turned  off by default, because
       they're really not all that interesting looking unless you're a fan  of
       those systems.

       There  are  command-line	options	for all	of these: e.g.,	-bsd, -no-bsd.
       (Also note the -only option.)

       Unlike the systems being	simulated, bsod	does not require a reboot  af-
       ter running.
