	Added a tzcoord.pl manpage, written by Gopal Narayanan
	(gopal@debian.org).  Also closed some other bugs reported through

2000 Jul 01
	Added -cloud_threshold option.

2000 Jun 28
	Added xp_getopt_long function.  This is a wrapper around the GNU
	getopt_long_only function.  I did this because the Sun and SGI C++
	compilers don't like getopt.h, but their C compilers accept it
	with no problem.

2000 Jun 26
	Xplanet 0.70 released.

2000 Jun 25
	Improved GIF reader/writer.

	xearth, which isn't under the GPL.

2000 Jun 19
	Added the other outer planets and Titan.

2000 Jun 17
	Added -cloud_ssec option.  This takes an image from 
	http://www.ssec.wisc.edu/data/comp/latest_moll.gif, removes the
	pink continent lines, reprojects to rectangular and overlays onto
	the image.  GIF support works well enough for this but otherwise
	doesn't work too well.

2000 Jun 16
	Added ImageMagick 5.2.0 support.

2000 Jun 14
	Added Jupiter and the Galilean satellites.  The -body option now
	takes names instead of numbers.

	under the GPL.

2000 Jun 09
	Added TIFF support.  Started adding other planets and satellites.

2000 Jun 06

	observer over the terminator and rotates the globe so that the
	terminator is vertical.  It's still off by a few degrees near
	solstice at mid-high latitudes.

2000 May 25
	Removed Imlib completely.  Xplanet now reads and writes JPEG and
	PNM files.  

2000 May 20
	Started writing new image library to replace Imlib for reading and
	writing image files.

2000 May 09
	Version 0.60 released.

2000 May 06
	Added decompose_pixmap routine which can be used instead of
	Imlib_create_image_from_drawable.  Also added 8 bit PseudoColor
	support.  
	
2000 Apr 30
	Added create_pixmap routine which can be used instead of 
	Imlib_render.

2000 Apr 23
	Xplanet should compile with either ImageMagick 4.2.* or
	ImageMagick 5.1.1 (API changed between the two).  Added
	--with-magick option to configure script.  Compiling with
	ImageMagick is disabled by default.  Fixed animate mode to work
	with Mesa 3.1.

2000 Apr 15
	Added code to use ImageMagick library to write output file in case
	DISPLAY variable isn't set.

2000 Apr 08
	Added "color" and "font" keywords to marker file.

2000 Mar 16
	Added changes suggested by Daniel Martin to compute proper -rotate
	values when running xplanetbg in -orbit mode.  Also modified
	aclocal.m4 to link to -lGL and -lGLU instead of -lMesaGL and
	-lMesaGLU.  

2000 Feb 22
	Xplanet 0.50 released.

2000 Feb 19
	Made Xplanet more compatible with xearth: getopt_long_only is now
	used to parse options, so options may now be preceded by "-" as
	well as "--".  Added support for the "align" keyword in the marker
	file.  Changed --marker_file to --markerfile and --star_den to
	--starfreq.

2000 Feb 16
	Edited autoconf macros to add --disable-anim.  Xplanet will now
	build without OpenGL/Mesa/glut.  The --animate option will not
	work in this case. 

2000 Feb 15
	Added ProjectionAzimuthal.class.  Also projections are now
	specified as an argument to --projection (i.e. --projection
	mercator instead of --mercator).

2000 Feb 02
	Added ProjectionMollweide class.

2000 Jan 19
	Added ProjectionMercator class.

2000 Jan 17
	Started restructuring the code - created Projection class and 
	derived classes ProjectionRectangular and ProjectionOrthographic.
	This will allow the easy incorporation of new projections, like
	Mercator & Mollweide.  Also moved X & imlib dependent code into
	xroutines.cc, to ease porting to other windowing systems.

2000 Jan 16
	The "mercator" projection is actually a rectangular projection.
	All instances of "mercator", including the --mercator option, have
	been changed to "rectangular".

2000 Jan 10
	Modified options.cc and xplanetbg.cc to use getopt_long().

2000 Jan 02

1999 Dec 02
	Fixed a bug where labels & markers weren't appearing for --window
	or --output options.  Added --swap option to swap planes when
	writing image files on big endian machines, --notransparency
	option to disable updating the background pixmap for Eterms and
	aterms, and --localtime option.  --longitude option no longer
	implies --orthographic.
	
1999 Nov 22
	Xplanet 0.42 released.

1999 Nov 20
	Added code to update background pixmaps for Eterms and aterms with
	transparency enabled.  Also generate icon pixmap for --window
	option.  Doesn't work with xplanetbg though.

1999 Oct 21
