- * 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.

- *   Many changes to fgMATERIAL.

- *
- * 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,

- * - propogated some of these changes out a bit further.

- * Revision 1.11  1998/08/25 20:53:29  curt
- * Shuffled $FG_ROOT file layout.

- * Revision 1.10  1998/08/10 20:33:09  curt
- * Rewrote star loading and rendering to:

- *
- * Revision 1.9  1998/08/06 12:45:20  curt

- * of stars.
- *
- * Revision 1.8  1998/07/13 21:00:10  curt
