The file Raster3D_2.7s.tar.gz contains the full source distribution for
version 2.7s of Raster3D.

  See CHANGELOG for a history of changes to the package.

- In a nutshell, the installation procedure is:

  	1)  Review the contents of Makefile.template
	2)  make help            (prints a list of OS names)
	3)  make OS              (where OS is your operating system name)
	4)  make all		 (builds the programs)
	5)  make install         (copies files to system directories)
	6)  modify user login environment to include R3D_LIB 
		e.g. setenv R3D_LIB /usr/local/share/Raster3D/materials

	7)  (optional)
	    modify ImageMagick delegates file so that ImageMagick recognizes
	    *.r3d files by default.  On my systems this file is in
	    	/usr/lib/ImageMagick-2.6.4/config/delegates.mgk
	    Add the following line
	    	<delegate decode="r3d" command='render -png "%o"<"%i"' />

- Changes in Version 2.7s compared to 2.7d
	+ compatible with gfortran compiler version 4.1.2
	+ scripts modified to work with ImageMagick version 6

This distribution has been tested on the following platforms:

	x86 x86_64 linux (Mandriva 2008 - gfortran, g77)

Previous versions have been tested under many other OS configurations.
2.7s is mostly a "bandaid release", to allow building on linux using
recent gfortran compilers. If you run into installation problems, please let
me know, particularly if you can also tell me what you did to fix it!

For optimal use of Raster3D you should also obtain 
John Cristy's ImageMagick package for image manipulation and viewing 
	(source distribution available from www.ImageMagick.org)
Some version of a TIFF library
Some version of a JPEG library
Some version of the PNG library (http://www.libpng.org/pub/png/libpng.html)
Version 2.0 or greater of Molscript (http://www.avatar.se/molscript)
