GDAL Ruby 1.9 fix gdal_ruby.i
/*
* $Id$
*
* ruby specific code for gdal bindings.
*/
/*
* $Log$
* Revision 1.2 2005/09/26 08:18:55 cfis
* Copied over code from the Python version of gdal_ruby.i. Will have to port the code to Ruby.
*
* 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.
*
