+/** \mainpage SimGear
+ * Simulation, Visualization, and Game development libraries.
+
+ * \section intro Introduction
+ *
+ * SimGear is a collection of libraries which provide a variety of
+ * functionality useful for building simulations, visualizations, and
+ * even games.  All the SimGear code is designed to be portable across
+ * a wide variety of platforms and compilers.  It has primarily been
+ * developed in support of the FlightGear project, but as development
+ * moves forward, we are generalizing the code to make more of it
+ * useful for other types of applications.
+ *
+ * Some of the functionality provide includes
+ *
+ * - Compiler and platform abstractions for many tricky differences.
+ * - A whole earth tiling/indexing scheme.
+ * - A console debugging output scheme that tracks severity and
+ *   category that can be completely compiled out for a final build release.
+ * - Code to manage "real" time and time zones.
+ * - Code to calculate accurate positions of sun, moon, stars, and
+ *   planets for a given time, date, season, earth location, etc.
+ * - Simple serial, file, and network I/O abstractions
+ * - Code to calculate magnetic variation.
+ * - A variety of coordinate conversion, vector, matrix type math routines.
+ * - An abstraction to hide platform dependent path naming schemes.
+ * - A C++ streams wrapper to handle compress input/output streams.
+ * - An optimized "property manager" which associates ascii property
+ *   names with their corresponding value.  This can be a great way to build
+ *   loose linkages between modules, or build linkages/connections that can
+ *   be determined from config files or at runtime.
+ * - Scene management and drawing routines:
+ *   - material property management
+ *   - object management
+ *   - terrain tile management and paging
+ *   - sky dome rendering (with ephemeral objects)
+ * - Code to handle screen dumps (and ultra-hires tile rendered screen dumps)
+ * - A sound effects manager.
+ * - A threading abstraction.
+ * - A simple but highly functional XML parser that interfaces nicely
+ *   with the property manager.
+
+ * \section supports Supported Platforms
+ * SimGear has been built on the following platforms:
+ *
+ *   - Linux (x86)
+ *   - Windows (MSVC, Cygwin, Mingwin)
+ *   - SGI (native compilers)
+ *   - Mac OS X
+ *   - FreeBSD
+ 
+ * \section depends Dependencies
+ *
+ * SimGear depends on several other open source packages.  These must
+ * be installed before SimGear can be installed:
+ *
+ *   - glut and opengl
+ *   - plib (http://plib.sf.net)
+ *   - metakit
+ *   - zlib
+ *   - libjpeg (optional)
+ *   - pthread (optional)
+ 
+ * \section license Licensing
+ *
+ * SimGear is licensed under the terms of the LGPL
+
+ * \section install Installation
+ *
+ * \subsection step1 Step 1: Opening the box
+ *  
+ * etc...
