+// 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!
