NAME
       xmoontool - Moon	For The	Sun / Werewolf Early Warning System

SYNOPSIS
       xmoontool [-mctU]

DESCRIPTION
       Xmoontool  is  a	 Xwindows application which displays information about
       the moon	in real	time.  When closed (iconic) it	displays  a  graphical
       representation  of  what	the moon would look like right now if you were
       to go outside and look at it. (Go on, try it, the fresh air may do  you
       some  good).   When  the	 window	is open, the same image	of the moon is
       displayed in the	upper right of the window, along with more verbose in-
       formation  about	 both the moon and the sun (the	bright yellow thing in
       the sky,	not the	thing you're staring at	right now.  It's  not  a  good
       idea  to	stare at the bright yellow thing).  The	open window display is
       updated approximately once per second, the icon is  updated  every  two
       minutes.

       Xmoontool  will	run on both monochrome and color displays.  Unless ex-
       plicity told to run in either the monochrome (-m)  or  the  color  (-c)
       mode,  xmoontool	 will  automatically  select the appropriate mode.  On
       color displays, the moon's face is rendered in eight colors in both the
       icon  and the open window.  The darkened	portion	of the moon is visible
       on color	displays as dark shades	of blue.  On monochrome	displays, only
       the illuminated portion of the face is drawn in.

       As an extra added bonus for users of color displays, the	Apollo 11 Com-
       memorative Red Dot has been added to the	face of	the moon  at  the  ap-
       proximate location of Tranquility Base, to mark the 20th	anniversary of
       An Historic Event.

       The image of the	moon's face used by xmoontool,	especially  the	 color
       version,	 is  quite  accurate.	It  was	 rendered  on  an Amiga	by Joe
       Hitchens, an artist of no small talent, from an illustration in an  as-
       tronomy textbook.

       If  invoked  with  the -t option, xmoontool will	start up in test mode.
       In test mode, the tool warps through time, updating the display as fast
       as  possible,  skipping	approximately  one  hour per cycle.  A menu is
       available on the	tool, for both the icon	and  the  open	window,	 which
       will  let  you  switch in and out of test mode at will.	This is	what's
       known as	a cheap	thrill,	and can	provide	endless	hours of entertainment
       (if you're easily entertained).

       The  option  -U	effects	 the  moon's and the sun's distances to	be ex-
       pressed in (statute) miles instead of the default kilometers.

       For those who are lycanthropically inclined, the	open window tells  you
       when  the  next full moon will occur.  This may or may not be something
       you'll want to know.

TEDIOUS	TECHNICAL CREDITS
       Believe it or not, xmoontool uses some actual science and even  authen-
       tic  mathematics.  If you're into that sort of thing, you might like to
       know that the following books were used by the original author to  cre-
       ate xmoontool:

       "Practical Astronomy With Your Calculator" by Peter Duffett-Smith, Sec-
       ond Edition, Cambridge University Press,	1981.

       "Astronomical Formulae for Calculators" by Jean Meeus,  Third  Edition,
       Willmann-Bell, 1985.

       "Planetary Programs and Tables from -4000 to +2800" by Pierre Bretagnon
       and Jean-Louis Simon, Willmann-Bell, 1986.

       "Celestial BASIC" by Eric Burgess, Revised Edition, Sybex, 1985.

       This one	was used by Joe	to render the moon image and by	me  to	locate
       the Apollo 11 landing site:

       "Astronomy: From	the Earth to the Universe" by Jay M. Pasachoff,	Second
       Edition,	Saunders College Publishing, 1983
