/* 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
* 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.
*
