-// Updates from Bernie Bright.
-//
-// Revision 1.2 1998/09/01 19:03:08 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 16:51:23 curt
-// Moved from ../Scenery
