Note About HTML Links
In order for the links to be resolved, if not done already by installing the lessons package under the Toolkit's ``doc/html'' directory, create a subdirectory called ``lessons'' under the ``doc/html'' directory of the ``cspice/'' tree and copy this document to that subdirectory before loading it into a Web browser.

Tutorial Contents -------------------- ----------------------------------- Intro to Toolkit lists all Toolkit applications and provides their location within the Toolkit Toolkit Applications provides an overview and a small example for most of the applications covered by this lesson SPK provides additional information for ``brief'' and ``spacit'' CK provides additional information for ``ckbrief''These tutorials are available from the NAIF server at JPL:
https://naif.jpl.nasa.gov/naif/tutorials.html User's Guides
All User's Guides are also included in the Toolkit in HTML format. The index page providing links to the HTML User's Guides is accessible using the ``User's Guides'' link on the top level HTML index ``cspice/doc/html/index.html''. Recommended Setup
All of the examples included in this lesson assume that the programs can be run by simply typing their name on the command line. To be able to do that the location of the Toolkit executables directory ``cspice/exe'' must be added to the system's environment variable ``path''. On a UNIX system you can add it using the ``set'' command as follows:
set path = ($path /my_directory/cspice/exe)where ``my_directory'' is the name of the directory under which the Toolkit is installed on your computer. On a Windows system you can add it by changing the environment variable ``PATH'' from the ``Advanced'' pane on the ``System Control'' panel to include:
drive:\my_directory\cspice\exewhere ``drive:\my_directory'' is the name of the directory under which the Toolkit is installed on your computer. Kernels Used

All examples in this lesson assume that these kernels are located in the directory from which you will run the programs. If you use kernels supplied in the lesson package, arranged under the ``kernels/<kernel_type>'' directory tree, you can copy them to your current directory by typing this command on your Unix computer:
% cp [path_to_lesson_dir]/kernels/*/*.* .or this command on your Windows computer:
% copy [path_to_lesson_dir]\kernels\*\*.* .where ``[path_to_lesson_dir]'' is the path to the directory under which the lesson package is installed. Note About ``Screen Shots'' Included in This Lesson

di_finalenc_nav_v3.bsp naif0008.tlsAlthough the ``states'' program is not intended to be used as executable -- the primary purpose of including it in the toolkit is to provide a simple source code example of using high level toolkit functions that compute state vectors -- as all other Toolkit applications it comes with a User's Guide (states.ug) describing its interface.
