# Introduction

This document describes the structure and contents of the latest version of the NAIF cspice Toolkit for INTEL MAC computers using MAC OS-X operating system and CC 64BIT compiler.

Most C compilers come with a large set of compilation options that can be used when compiling source code. The compiler options we (NAIF) used when creating the various object libraries are discussed in the section "LIB" that appears later in this document.

# Using the Toolkit

Top

## All Users

After completing your Toolkit installation it is extremely important that you carefully read the ``whats.new'' description of changes and additions if you haven't done so prior to the installation.

The Toolkit contains two styles of documentation: a plain text version and a hyper-linked HTML version. NAIF recommends you use the HTML version because of the convenience of the hyper-linking. To do that load the top level index of the HTML documentation -- ``doc/html/index.html'' -- into a web browser.

Top

## Repeat Users

If you are not a first time user, save your own application executables in a safe place and then re-link those application programs to the newly installed library, creating new executables. NAIF suggests you carefully re-test any critical applications to be sure they are working correctly -- you may have unknowingly taken advantage of a bug in the old library that has since been fixed.

Be aware that sometimes a bug fix or a small algorithmic change in the new SPICE code could result in small changes in numeric results; this could show up in your regression test cases.

Top

## First Time Users

NAIF provides several means to help you get started using SPICE -- tutorials, ``open book'' programming lessons, several ``cookbook programs,'' and extensive documentation. Which of these will best suit your needs, and in what order you should use these materials, depends on your training/background and your immediate needs for using SPICE. NAIF suggests you become familiar with the offerings from the NAIF website (http://naif.jpl.nasa.gov), most particularly the tutorials and lessons collections. You might also take time to read the ``Introduction to the SPICE System'' document.

Please note that NAIF assumes you are familiar with how to write code in the language you have chosen, and that you know how to compile, link (``make'') and execute programs on your computer. If this is not the case you should first take some generic programming lessons before trying to tackle SPICE.
