 * $Log$
 * Revision 1.4  2006/11/23 22:50:53  tamas
 * C# ExportToWkb support
 *
 * Revision 1.3  2006/09/07 10:26:31  tamas
 * Added default exception support
 *
 * Revision 1.2  2005/09/06 01:51:04  kruland
 * Removed GetDriverByName, GetDriver, Open, OpenShared because they are defined
 * in ogr now.
 *
 * Revision 1.1  2005/09/02 16:19:23  kruland
 * Major reorganization to accomodate multiple language bindings.
 * Each language binding can define renames and supplemental code without
 * having to have a lot of conditionals in the main interface definition files.
