-// Revision 1.27  1999/02/05 21:28:52  curt
-// Modifications to incorporate Jon S. Berndts flight model code.
-//
-// Revision 1.26  1999/02/02 20:13:30  curt
-// MSVC++ portability changes by Bernie Bright:
-//
-// Lib/Serial/serial.[ch]xx: Initial Windows support - incomplete.
-// Simulator/Astro/stars.cxx: typo? included <stdio> instead of <cstdio>
-// Simulator/Cockpit/hud.cxx: Added Standard headers
-// Simulator/Cockpit/panel.cxx: Redefinition of default parameter
-// Simulator/Flight/flight.cxx: Replaced cout with FG_LOG.  Deleted <stdio.h>
-// Simulator/Main/fg_init.cxx:
-// Simulator/Main/GLUTmain.cxx:
-// Simulator/Main/options.hxx: Shuffled <fg_serial.hxx> dependency
-// Simulator/Objects/material.hxx:
-// Simulator/Time/timestamp.hxx: VC++ friend kludge
-// Simulator/Scenery/tile.[ch]xx: Fixed using std::X declarations
-// Simulator/Main/views.hxx: Added a constant
-//
-// Revision 1.25  1998/12/09 18:50:15  curt
-// Converted "class fgVIEW" to "class FGView" and updated to make data
-// members private and make required accessor functions.
-//
-// Revision 1.24  1998/12/05 15:54:04  curt
-// Renamed class fgFLIGHT to class FGState as per request by JSB.
-//
-// Revision 1.23  1998/11/23 21:48:28  curt
-// Borland portability tweaks.
-//
-// Revision 1.22  1998/11/07 19:07:07  curt
-// Enable release builds using the --without-logging option to the configure
-// script.  Also a couple log message cleanups, plus some C to C++ comment
-// conversion.
-//
-// Revision 1.21  1998/11/06 21:17:42  curt
-// Converted to new logstream debugging facility.  This allows release
-// builds with no messages at all (and no performance impact) by using
-// the -DFG_NDEBUG flag.
-//
-// Revision 1.20  1998/11/06 14:47:02  curt
-// Changes to track Bernie's updates to fgstream.
-//
-// Revision 1.19  1998/10/16 23:27:21  curt
-// C++-ifying.
-//
-// Revision 1.18  1998/10/16 00:52:20  curt
-// Converted to Point3D class.
-//
-// Revision 1.17  1998/09/24 15:36:19  curt
-// Converted to c++ style comments.
-//
-// Revision 1.16  1998/09/24 15:25:24  curt
-// Miscellaneous tweaks.
-//
-//
-// Revision 1.15  1998/09/17 18:25:12  curt
-// Fixed output message.
-//
-// Revision 1.14  1998/09/15 04:26:22  curt
-// New textured moon and rewritten/restructured Astro code contributed by Durk
-// Talsma.
-//
-// Revision 1.13  1998/09/01 19:03:04  curt
-// Changes contributed by Bernie Bright <bbright@c031.aone.net.au>
-//  - The new classes in libmisc.tgz define a stream interface into zlib.
-//    I've put these in a new directory, Lib/Misc.  Feel free to rename it
-//    to something more appropriate.  However you'll have to change the
-//    include directives in all the other files.  Additionally you'll have
-//    add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
-//
-//    The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
-//    test so I've included the required changes in config.tgz.
-//
-//    There are a fair few changes to Simulator/Objects as I've moved
-//    things around.  Loading tiles is quicker but thats not where the delay
-//    is.  Tile loading takes a few tenths of a second per file on a P200
-//    but it seems to be the post-processing that leads to a noticeable
-//    blip in framerate.  I suppose its time to start profiling to see where
-//    the delays are.
-//
-//    I've included a brief description of each archives contents.
-//
-// Lib/Misc/
-//   zfstream.cxx
-//   zfstream.hxx
-//     C++ stream interface into zlib.
-//     Taken from zlib-1.1.3/contrib/iostream/.
-//     Minor mods for STL compatibility.
-//     There's no copyright associated with these so I assume they're
-//     covered by zlib's.
-//
-//   fgstream.cxx
-//   fgstream.hxx
-//     FlightGear input stream using gz_ifstream.  Tries to open the
-//     given filename.  If that fails then filename is examined and a
-//     ".gz" suffix is removed or appended and that file is opened.
-//
-//   stopwatch.hxx
-//     A simple timer for benchmarking.  Not used in production code.
-//     Taken from the Blitz++ project.  Covered by GPL.
-//
-//   strutils.cxx
-//   strutils.hxx
-//     Some simple string manipulation routines.
-//
-// Simulator/Airports/
-//   Load airports database using fgstream.
-//   Changed fgAIRPORTS to use set<> instead of map<>.
-//   Added bool fgAIRPORTS::search() as a neater way doing the lookup.
-//   Returns true if found.
-//
-// Simulator/Astro/
-//   Modified fgStarsInit() to load stars database using fgstream.
-//
-// Simulator/Objects/
-//   Modified fgObjLoad() to use fgstream.
-//   Modified fgMATERIAL_MGR::load_lib() to use fgstream.
-//   Many changes to fgMATERIAL.
-//   Some changes to fgFRAGMENT but I forget what!
-//
-// Revision 1.12  1998/08/27 17:02:01  curt
-// Contributions from Bernie Bright <bbright@c031.aone.net.au>
-// - use strings for fg_root and airport_id and added methods to return
-//   them as strings,
-// - inlined all access methods,
-// - made the parsing functions private methods,
-// - deleted some unused functions.
-// - propogated some of these changes out a bit further.
-//
-// Revision 1.11  1998/08/25 20:53:29  curt
-// Shuffled $FG_ROOT file layout.
-//
-// Revision 1.10  1998/08/10 20:33:09  curt
-// Rewrote star loading and rendering to:
-//   1. significantly improve load speed
-//   2. transition from no stars to stars through eight stages.
-//
-// Revision 1.9  1998/08/06 12:45:20  curt
-// Modified to bring in stars in 8 increments based on magnitude, not number
-// of stars.
-//
-// Revision 1.8  1998/07/13 21:00:10  curt
-// Wrote access functions for current fgOPTIONS.
-//
-// Revision 1.7  1998/05/29 20:35:42  curt
-// Added zlib support for reading in compressed data files.
-//
-// Revision 1.6  1998/05/13 18:25:35  curt
-// Root path info moved to fgOPTIONS.
-//
-// Revision 1.5  1998/04/28 01:19:03  curt
-// Type-ified fgTIME and fgVIEW
-//
-// Revision 1.4  1998/04/26 05:10:02  curt
-// "struct fgLIGHT" -> "fgLIGHT" because fgLIGHT is typedef'd.
-//
-// Revision 1.3  1998/04/25 22:06:26  curt
-// Edited cvs log messages in source files ... bad bad bad!
-//
-// Revision 1.2  1998/04/24 00:45:03  curt
