1. Installation Requirements

 We assume that you have a working installation of CMUCL:

     http://www.cons.org/cmucl/

 If you want the rendering-window to work you need a working installation
 of CL-SDL:

     http://cl-sdl.sourceforge.net/
     
 NOTE FOR NON-CMUCL USERS: Getting GRT to work on other Common Lisp
 implementations should be relatively easy. If you do port GRT to
 another implementation, please let us know, so that we can integrate
 it into the next release.


2. Installation Procedure

 There is none as of yet. You can load GRT into a running lisp by

    (load "grt.lisp")


3. Testing Installation

 Enter the directory where you unpacked the sources, and run:

    lisp -load grt.lisp -load examples.lisp -eval '(all-examples :screen t)'

 This should render example scenes defined in the files examples.lisp
 into local directory "examples". If CL-SDL is installed you should see
 each image as it is being rendered, if not you get a warning about
 ignored ":screen".
