-/* 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

- * 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.
- *
