 * Revision 1.2  2005/09/02 21:42:42  kruland
 * The compactdefaultargs feature should be turned on for all bindings not just
 * python.
 *
 * 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.
