 * $Log$
 * Revision 1.6  2006/11/19 20:07:35  ajolma
 * instead of renaming, create GetField as a copy of GetFieldAsString
 *
 * Revision 1.5  2006/11/19 17:42:24  ajolma
 * There is no sense in having typed versions of GetField in Perl, renamed GetFieldAsString to GetField
 *
 * Revision 1.4  2005/09/21 19:04:12  kruland
 * Need to %include cpl_exceptions.i
 *
 * Revision 1.3  2005/09/21 18:00:05  kruland
 * Turn on UseExceptions in ogr init code.
 *
 * Revision 1.2  2005/09/13 17:36:28  kruland
 * Whoops!  import typemaps_perl.i.
 *
 * Revision 1.1  2005/09/13 16:08:45  kruland
