00071  * Revision 1.4  2006/05/22 15:08:01  strk
00072  * Print colon after exception name (as it has always been)
00073  *
00074  * Revision 1.3  2006/04/05 09:34:20  strk
00075  * GEOSException derived from std::exception again, hopefully the correct way now
00076  *
00077  * Revision 1.2  2006/04/04 08:16:46  strk
00078  * Changed GEOSException hierarchy to be derived from std::runtime_exception.
00079  * Removed the GEOSException::toString redundant method (use ::what() instead)
00080  *
00081  * Revision 1.1  2006/03/09 16:46:49  strk
00082  * geos::geom namespace definition, first pass at headers split
