138 // tweaked in data file comment handling.
140 // Revision 1.5 1998/09/02 14:35:38 curt
141 // Rewrote simple airport loader so it can deal with comments and blank lines.

144 // Changes contributed by Bernie Bright <bbright@c031.aone.net.au>
145 // - The new classes in libmisc.tgz define a stream interface into zlib.
146 // I've put these in a new directory, Lib/Misc. Feel free to rename it
147 // to something more appropriate. However you'll have to change the
148 // include directives in all the other files. Additionally you'll have
149 // add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
151 // The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
152 // test so I've included the required changes in config.tgz.
154 // There are a fair few changes to Simulator/Objects as I've moved
155 // things around. Loading tiles is quicker but thats not where the delay
156 // is. Tile loading takes a few tenths of a second per file on a P200
157 // but it seems to be the post-processing that leads to a noticeable
158 // blip in framerate. I suppose its time to start profiling to see where
161 // I've included a brief description of each archives contents.
166 // C++ stream interface into zlib.
167 // Taken from zlib-1.1.3/contrib/iostream/.
168 // Minor mods for STL compatibility.
169 // There's no copyright associated with these so I assume they're
170 // covered by zlib's.
174 // FlightGear input stream using gz_ifstream. Tries to open the
175 // given filename. If that fails then filename is examined and a
176 // ".gz" suffix is removed or appended and that file is opened.
179 // A simple timer for benchmarking. Not used in production code.
180 // Taken from the Blitz++ project. Covered by GPL.
184 // Some simple string manipulation routines.
186 // Simulator/Airports/
187 // Load airports database using fgstream.
188 // Changed fgAIRPORTS to use set<> instead of map<>.
189 // Added bool fgAIRPORTS::search() as a neater way doing the lookup.
190 // Returns true if found.
193 // Modified fgStarsInit() to load stars database using fgstream.
195 // Simulator/Objects/
196 // Modified fgObjLoad() to use fgstream.
197 // Modified fgMATERIAL_MGR::load_lib() to use fgstream.
198 // Many changes to fgMATERIAL.
199 // Some changes to fgFRAGMENT but I forget what!
201 // Revision 1.3 1998/08/27 17:01:55 curt
202 // Contributions from Bernie Bright <bbright@c031.aone.net.au>
203 // - use strings for fg_root and airport_id and added methods to return
205 // - inlined all access methods,
206 // - made the parsing functions private methods,
207 // - deleted some unused functions.
208 // - propogated some of these changes out a bit further.
210 // Revision 1.2 1998/08/25 20:53:24 curt

240 // Revision 1.2 1998/04/28 21:42:50 curt
241 // Wrapped zlib calls up so we can conditionally comment out zlib support.
243 // Revision 1.1 1998/04/25 15:11:11 curt
