// Revision 1.3  1998/10/16 00:54:41  curt
// Converted to Point3D class.
//
// Revision 1.2  1998/09/01 19:03:10  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 1.1  1998/08/25 16:51:26  curt
// Moved from ../Scenery
//
// Revision 1.4  1998/05/24 02:49:10  curt

//
// Revision 1.3  1998/05/23 14:09:21  curt
// Added tile.cxx and tile.hxx.
// Working on rewriting the tile management system so a tile is just a list
// fragments, and the fragment record contains the display list for that
// fragment. 
//
// Revision 1.2  1998/05/02 01:52:15  curt
// Playing around with texture coordinates.
//

// Edited cvs log messages in source files ... bad bad bad!
//
// Revision 1.10  1998/04/24 00:51:07  curt
// Wrapped "#include <config.h>" in "#ifdef HAVE_CONFIG_H"
// Tweaked the scenery file extentions to be "file.obj" (uncompressed)
// or "file.obz" (compressed.)
//
// Revision 1.9  1998/04/22 13:22:45  curt
// C++ - ifing the code a bit.

// system and commandline/config file processing code.

// Changed #ifdef FILE_H to #ifdef _FILE_H
//
// Revision 1.3  1998/01/19 19:27:17  curt

// This should simplify things tremendously.
