81 * Revision 1.4 2006/05/22 15:08:01 strk
82 * Print colon after exception name (as it has always been)
83 *
84 * Revision 1.3 2006/04/05 09:34:20 strk
85 * GEOSException derived from std::exception again, hopefully the correct way now
86 *
87 * Revision 1.2 2006/04/04 08:16:46 strk
88 * Changed GEOSException hierarchy to be derived from std::runtime_exception.
89 * Removed the GEOSException::toString redundant method (use ::what() instead)
90 *
91 * Revision 1.1 2006/03/09 16:46:49 strk
92 * geos::geom namespace definition, first pass at headers split
