95 * Revision 1.2 2006/04/03 15:54:33 strk
96 * - getArgGeometry() parameter type changed from 'int' to 'unsigned int'
97 * - Added port informations
98 * - minor assertions checking
99 * - minor cleanups
100 *
101 * Revision 1.1 2006/03/09 16:46:49 strk
102 * geos::geom namespace definition, first pass at headers split
