 * Name:     cpl.i
 * Project:  GDAL Python Interface
 * Purpose:  GDAL Core SWIG Interface declarations.
 * Author:   Kevin Ruland, kruland@ku.edu
 *

 *
 * $Log: cpl.i,v $
 * Revision 1.5  2006/01/17 04:38:09  cfis
 * Switched #ifdef declarations to have a section for Ruby to be more consistent with other SWIG interface files.
 *
 * Revision 1.4  2006/01/16 08:07:04  cfis
 * Exposed CPLHexToBinary and CPLHexToBinary to scripting languages.
 *
 * Revision 1.3  2005/10/02 23:31:27  cfis
 * Updated the renames to include support for Ruby.
 *
 * Revision 1.2  2005/02/16 16:54:48  kruland
 * Removed the python code from the wrapper for now.  Wrapped a simple version
 * of PushErrorHandler(char const*) which allows assignment of the CPL defined
 * error handlers.
