NAME
       starwars - draws a perspective text crawl, like at the beginning of the
       movie

SYNOPSIS
       starwars [-display host:display.screen] [-window] [-root] [-visual vis‐
       ual]  [-delay  microseconds] [-program command] [-size integer ] [-col‐
       umns integer] [-wrap | -no-wrap] [-left |  -center  |  -right]  [-lines
       integer]	 [-spin	 float]	 [-steps  integer] [-delay usecs] [-font xlfd]
       [-no-textures] [-no-smooth] [-no-thick] [-fps]

DESCRIPTION
       The starwars program runs another program to generate a stream of text,
       then  animates  that text receeding into the background at an angle, in
       front of a star field.

OPTIONS
       starwars accepts the following options:

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

       -root   Draw on the root window.

       -install
	       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
	       visual.

       -program sh-command
	       The command to run to  generate	the  text  to  display.	  This
	       option  may  be	any string acceptable to /bin/sh.  The program
	       will be run at the end of a pipe, and any  characters  that  it
	       prints  to  stdout  will be printed on the starwars window.  If
	       the program exits, it will be launched again after we have pro‐
	       cessed all the text it produced.

	       Note  that  starwars  is not a terminal emulator: programs that
	       try to directly address the screen will not do what  you	 might
	       expect.	This program merely draws the characters on the screen
	       left to right, top to bottom, in perspective.  Lines (may) wrap
	       when they reach the right edge.

	       In  other  words,  programs like fortune(1) will work, but pro‐
	       grams like top(1) won't.

	       Some examples:
	       starwars -program 'cat /usr/src/linux*/README'
	       starwars -columns 30 -program 'ping www.starwars.com'
	       starwars -left -no-wrap -program 'ps -auxwwf'
	       starwars -left -no-wrap -columns 45 -program 'top -bn1'
	       starwars -left -columns 40 -program 'od -txC /dev/urandom'
	       starwars -font fixed -program 'od -txC /dev/urandom'

       -size integer
	       How large a font to use, in points.  (Well, in  some  arbitrary
	       unit   we're  calling  "points"	for  the  sake	of  argument.)
	       Default: 24.

       -columns integer
	       How many columns of text should be visible on the  bottom  line
	       of the screen.  Default: 60.

	       Only  one  of  -columns and -size may be specified; if both are
	       specified, -columns takes priority.

       -wrap   Word-wrap lines when they reach the rightmost column.  This  is
	       the default.

       -no-wrap
	       Do  not	word-wrap: just let the lines go off the right side of
	       the screen.

       -left | -center | -right
	       Whether to align the text flush left, centered, or flush right.
	       The default is centered.

       -lines integer
	       How  many  lines	 should	 be allowed to be on the screen before
	       they fall off the end.  The default is 125.

       -spin float
	       The star field on the background slowly rotates.	 This  is  how
	       fast.  The default is 0.03.

       -steps integer
	       How  many  steps	 should	 be used to scroll a single line.  The
	       default is 35.  If the animation looks jerky to	you,  increase
	       this number.

       -delay usecs
	       The  delay  between  steps  of  the animation; default is 40000
	       (1/25th second.)

       -font font-name
	       The name of the font to use.  For best effect, this should be a
	       large font (at least 36 points.)	 The bigger the font, the bet‐
	       ter looking the characters will be.  Note that the size of this
	       font affects only the clarity of the characters, not their size
	       on the screen: for that, use the -size or -columns options.

	       Default: -*-utopia-bold-r-normal-*-*-720-*-*-*-*-iso8859-1

       -no-textures
	       Instead of texture-mapping a real font to render the text,  use
	       a  built-in  font composed of line segments.  On graphics cards
	       without texture support, the line-segment font will  have  much
	       better performance.

       -no-smooth
	       When using the line-segment font, turn off anti-aliasing of the
	       lines used to draw the font.  This will make the text blockier,
	       but may improve performance.

       -no-thick
	       When  using  the line-segment font, turn off use of thick lines
	       for the characters that are close to the foreground.  This will
	       make  the  text appear unnaturally skinny, but may improve per‐
	       formance.

       -fps    Display the current frame rate, CPU load, and polygon count.

ENVIRONMENT
       DISPLAY to get the default host and display number.

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