WHAT IS IT
----------

This toolbox contains tools for tracking satellites, simulating rocket
trajectories and calculating spacecraft specific parameters such as thermal
control and visibility. The toolbox also contains assisting routines such as
sorting satellites and plotting rocket motor thrust-curves and date conversion.



INSTALLATION
------------

0. >>Skip to step 3 if this is the first time you install this toolbox!<<
   First you have to remove the entries from your matlab path which corresponds
   to the directory of this toolbox and its subsequent directories which might
   be there. This is to ensure that matlab won't complain later over
   non-existing directories if should happen the directory strucuter of this
   toolbox is altered in nextcoming versions. To do this, use "editpath" or
   "pathtool" which ever is convenient for you. The directories to remove are:
      * .../space/
      * .../space/atmos/
      * .../space/maps/

1. Next, you have to backup any files you've added to the toolbox or changes
   made to existing files (must not be redistributed without my
   approval!).

2. After this is done, completely delete the existing toolbox directory.

3. Place the space.#.#.zip archive file in the directory where you want
   to keep this toolbox. If you place it under "c:/matlab/" then the toolbox
   will appear in the directory "c:/matlab/space/". According to the example
   in step 0, you should place it in the directory given by
