// - 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 1.2 1998/08/27 17:01:56 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 1.1 1998/08/25 17:19:14 curt
// Moved from ../Main/
//
// Revision 1.7 1998/07/24 21:39:09 curt

// #include <string.h> before various STL includes.
// Make HUD default state be enabled.
//
// Revision 1.4 1998/06/03 00:47:14 curt
// Updated to compile in audio support if OSS available.
// Updated for new version of Steve's audio library.
